Which is the correct definition of perpendicular lines?
A. A part of a line that is bounded by two distinct endpoints.
B. A set of points that extends infinitely in two directions.
C. Two lines that intersect at a right angle.
D. Two lines that never cross.
(Note: the selected answer is the image is not guaranteed to be correct)
By definition of perpendicularity, plane, point and line, we find that two lines are perpendicular if they intersect at a right angle. (Correct choice: C)
When are two lines on a plane perpendicular?
According to Euclidean geometry, two pairs of opposite angles are created by generating two lines with different slopes on the same plane. Two lines with same slope never cross on the plane and are known as parallel lines.
Opposite angles have the same measure and the two lines are perpendicular to each other if and only if each pair of opposite angles are right angles. Right angles have a measure of 90° (π / 2 radians), then each of the four angles must have a measure of 90° (π / 2 radians).
In summary, two lines set on a plane are perpendicular to each other if they intersect at a right angle.

from the top of a 160-ft lighthouse, the angle of depression to a ship in the ocean is 26°. how far is the ship from the base of the lighthouse? (round your answer to the nearest foot.)
The distance between both the ship and the lighthouse's base is 328 feet.
What is considered as angle of depression?If a line of sight is slightly down from the horizontal line, it forms an angle with the horizontal line. If the object being observed is below the observer's level, the angle formed between both the horizontal line and also the observer's lines of sight is known as the angle of depression.
Given the circumstances, a right angle triangle is constructed. The lighthouse's height represents the right angle triangle's opposite side.
The adjacent side of a right angle triangle is represented by the horizontal distance, h, between both the ship and thus the base of the lighthouse.
Because they are opposite angles, is if angle of depression to the fire is 26°, the angle of elevation of a lighthouse from the ship is also 26°.
To calculate h, we would use
the trigonometric tangent ratio;
Tan θ = opposite side/adjacent side. Therefore,
Tan 26 = 160/h
h = 160/tan26 = 160/0.4877
h = 328 feet
Therefore, the distance between the ship and the base of the light house is 328 feet.

The formula for simple interest is i = prt, where i is the interest earned,p is the principal, r is the interest rate and t is the number of years. solve the formula for p in terms of r, i and y.
The principal in terms of Simple Interest, Time, and Rate can be expressed as p=(i×100)/(r×t).
Whenever a loan is given to a person it is given for some specific amount of time at a specific rate of interest which is to be paid along with the principal amount. Simple Interest is the method of calculating the interest amount on a loan given for a specific period.
It involves the multiplication of the principal amount, rate of interest, and the time for which the loan is given divided by 100.
Here Simple interest is denoted by i, time in years is denoted by t, the principal is denoted by p, and the rate of interest is denoted by r.
The formula of simple Interest is given by:
Simple interest = (Principal×Rate×Time)/100
i=(p×r×t)/100
Now principal can be denoted as:
p=(i×100)/(r×t)
Thus, the Principal in terms of Simple Interest, Time, and Rate can be expressed as p=(i×100)/(r×t).

Find the equation of the line.
Use exact numbers.
y= x+
Answer:
y = 3/4x -2
Step-by-step explanation:
We first find the slope of the line using two points
(0,-2) and (8,4)
m = ( y2-y1)/(x2-x1)
m = ( 4---2)/(8 - 0)
= (4+2)/(8)
= 6/8
= 3/4
We can write the equation in slope-intercept form using
y = mx+b where m is the slope and b is the y-intercept
b is where it crosses the y axis. It crosses at -2
y = 3/4x -2
Write an equation in slope-intercept form for the line parallel to the given line
that passes through the given point.
y = - 4x + 5, (0,4)
A. Y= -4x + 4
B. y = -1/4x + 4
C. Y= 1/4x + 4
D. Y= 4x + 4
===========================================================
Explanation:
The given equation y = -4x+5 has a slope of -4. Compare it to y = mx+b and m is the slope.
Parallel lines have equal slopes, but different y intercepts. The answer will have a slope of -4.
The point we want the answer to go through is (x1,y1) = (0,4)
We'll plug the following values
m = -4x1 = 0y1 = 4into the point slope formula below. Solve for y.
y - y1 = m(x - x1)
y - 4 = -4(x - 0)
y - 4 = -4x
y = -4x+4 which is choice A

The measure of angle 1 is 76⁰, the measure of angle 2 is 104⁰, the measure of angle 3 is 76⁰ and the measure of angle 4 is 104⁰.
Sum of angles in circleThe sum of angles in a circle is 360 degrees.
In other words, we can say that, the sum of the measures of the central angles of a circle with no points in common is 360 degrees.
In the given diagram, angle 1, angle 2, angle 3 and angle 4 will sum to 360 degrees.
m∠1 + m∠2 + m∠3 + m∠4 = 360⁰
another interesting to observe is that;
m∠1 = m∠3
m∠2 = m∠4
if m∠1 = 76⁰, then
m∠3 = 76⁰
m∠2 + m∠4 = 360 - (76 + 76)
m∠2 + m∠4 = 208
m∠2 = m∠4 = 208/2 = 104⁰

He has enough money to buy all the paving stone for the rectangular garden.
How to use area to know if the stone is enough for the rectangular path?The garden path is rectangular.
He wants to cover the path with a paving stone. The paving stone is square in shape and have side of 40 cm.
Therefore,
area of the square stone = l²
where
l = side lengthTherefore,
area of the square stone = 40²
area of the square stone = 1600 cm²
area of the rectangular garden = lw
where
l = lengthw = widthTherefore,
area of the rectangular garden = 800 × 120
area of the rectangular garden = 96000
area of the rectangular garden = 96000 cm²
Therefore,
number of paving stone required = 96000 / 1600
number of paving stone required = 60
Hence,
cost of covering the path = 4.50 × 60 = £ 270
Therefore, he has enough money to buy all the paving stone for the rectangular garden.

The 2 ft 3 in. semicircular section of the window and the 4 ft 6 in. by 4 ft 6 in. of the square section gives;
a. The area of the semicircular pane is approximately 1145.1 in.²
b. The square section is 2916
c. The entire window has a perimeter of approximately 354.82 inches
How can the area and the perimeter of the shapes be found?a. The given radius of the semicircular pane, r = 2 ft. 3 in. = 27 in.
The area of a semicircle, A = 0.5•π•r²The area of the semicircular pane is therefore;
A = 0.5 × π × 27² ≈ 1145.1
The area of the semicircular pane is approximately 1145.1 in.²b. The area, A, of the 9 panes of glass, disregarding the window trim is found using the equation for the area of a square, as follows;
A = Side × Side
The area of the 9 panes is therefore;
A = 4 ft. 6 in. × 4 ft. 6 in.
Which gives;
A = 54 in. × 54 in. = 2916 in.²
The area of the square section is 2916 in²c. The perimeter of the entire window, P, is given by the sum of the perimeter of the semicircular pane, P1, and the perimeter of the 9 square window panes, P2, as follows
P1 = 54 + π×27
P2 = 4 × 54
P = P1 + P2Which gives;

Part (a)
r = radius
h = height = 5r
SA = Surface area of a cylinder
SA = 2pi*r^2 + 2pi*r*h
SA = 2pi*r^2 + 2pi*r*5r
SA = 2pi*r^2 + 10pi*r^2
SA = (2pi+10pi)*r^2
SA = 12pi*r^2
Answer: 12pi*r^2====================================================
Part (b)
r = radius
h = height = 5r
V = volume of a cylinder
V = pi*r^2*h
V = pi*r^2*5r
V = 5pi*r^3
Set this equal to the stated volume of 1715pi cubic cm and solve for r.
The pi terms cancel
So,
V = 5pi*r^3
1715pi = 5pi*r^3

Answer:
∠ B = 23°
Step-by-step explanation:
vertical angles are congruent , so
∠ B = ∠ A , that is
5x - 17 = x + 15 ( subtract x from both sides )
4x - 17 = 15 ( add 17 to both sides )
4x = 32 ( divide both sides by 4 )
x = 8
Then
∠ B = 5x - 17 = 5(8) - 17 = 40 - 17 = 23°
Vertically opposite angles are equal
So,[tex]x + 15 = 5x - 17 \\ 15 + 17 = 5x - x \\ 32 = 4x \\ x = 8[/tex]
Therefore;[tex] \sf \: \angle \: a = x + 15 = > 8 + 15 = 23 \degree[/tex]
