Angle 1 is in a triangle with angle 4 and a 53 degrees angle. What is the sum of the measures of those two angles?
The value of angles are in given triangle as:
Angle 1 = 37°, angle 2 = 127°, angle 3 = 23°, and angle 4 = 90°.
Given that the triangle attached below.
Also given angle one with angle four and a 53° angle.
Since the sum all three angle of triangle is equal to 180°.
In triangle ABC,
∠A + ∠B + ∠C = 180
Angle 1 + 90 + 53 = 180
Angle 1 = 37°
Also the angle 4 is equal to 90°.
The angle 2 is equal to 127°, because 180 - 53 = 127°
Now, in triangle ACD,
∠C=127° and ∠D = 30
∠A + ∠C + ∠D = 180
Angle 3 + 127 + 30 = 23
Hence, the value of angles are:
Angle 1 = 37°
Angle 2 = 127°
Angle 3 = 23°
And angle 4 = 90°

Khara buys a shirt for $24 and 2 pair of pants. She doesn't remember the cost of the pants. She knows she spent a total of $102. Which equation would you use to find the cost of a pair of pants?
Answer:
39 per pair of pants .
Step-by-step explanation:
First of all you would take 102 and subtract 24 which equals 78 . Then you would divide 78 by 2 and your answer will be 39 . To check your answer you will take 24 39 , 39 and add it all together . if it comes out to 102 you have the correct answer . So you are using subtraction division and addition

Given: AB ≅ BC , AE ≅ FC Prove: m∠AEC=m∠AFC
Answer:
EC/AB = FC/MA
Step-by-step explanation:
We are given AB
≅
BC that means that side AB and side BC are equal also we know that angle opposite to equalt
sides are equal.
Hence, ∠BAE=∠BCE-------(1)
Also ∠AEB=∠CEB.
Now we are given that: ∠ABC = 130°30’ i.e. in degrees it could be given as:
60'=1°
30'=(1/2)°=0.5°
Hence ∠ABC = 130°30’=130+0.5=130.5°
Also we know that sum of all the angles in a triangle is equal to 180°.
Hence,
∠BAE+∠BCE+∠ABC=180°.
2∠BAE+130.5=180 (using equation (1))
2∠BAE=49.5
∠BAE=24.75° (DIVIDE BOTH SIDE BY 2)
Now in triangle ΔBEC we have:
∠BEC=90° , ∠BCE=24.75°
SO,
∠BEC+∠BCE+∠EBC=180°.
Hence, 90+24.75+∠EBC=180
∠EBC=180-(90+24.75)
∠EBC=65.25°
Now we are given AE = 10 in
Also ∠BEA= 90°.
And ∠BAE=24.75°; hence using trignometric identity to find the measure of side BE.
\begin{gathered}\tan 24.75=\dfrac{BE}{AE}=\dfrac{BE}{10}\\\\BE=10\tan 24.75-------(2)\end{gathered}tan24.75=AEBE=10BEBE=10tan24.75−−−−−−−(2)
similarly in right angled triangle ΔBEC we have:
\begin{gathered}\tan 24.75=\dfrac{BE}{EC}\\\\\tan 24.75=\dfrac{BE}{EC}\\\\EC=\dfrac{BE}{\tan 24.75}------(3)\end{gathered}tan24.75=ECBEtan24.75=ECBEEC=tan24.75BE−−−−−−(3)
Hence, using equation (2) in equation (3) we get:
EC=10 \text{in.}EC=10in.
Hence AC=AE+EC=10+10=20 in.
Hence side AC=20 in.

Sandy bought 12 7/8 pounds of peaches to make jam. She and her mother ate 0.75 of a pound of the peaches before making the jam. They used 9 3/8 pounds of the peaches to make the jam. How many pounds of peaches were left over?
A. 3 1/4
B. 3
C. 2 3/4
D. 2 1/4
Answer:
C
Step-by-step explanation:
initial amount: 12 7/8 lbs
ate: 0.75 lbs= 3/4 lbs = 6/8 lbs
used: 9 3/8 lbs
remainder: 12 7/8 - 9 3/8 - 6/8
= 3 1/8 - 3/8
=2 6/8 = 2 3/4 = C

5x+9=24 sovle for x ?????????????
Answer:
x = 3
Step-by-step explanation:
Solution for 9+5x=24 equation:
Simplifying
9 + 5x = 24
Solving
9 + 5x = 24
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-9' to each side of the equation.
9 + -9 + 5x = 24 + -9
Combine like terms: 9 + -9 = 0
0 + 5x = 24 + -9
5x = 24 + -9
Combine like terms: 24 + -9 = 15
5x = 15
Divide each side by '5'.
x = 3
Simplifying
x = 3
The solution is : in the equation 5x+9=24 the value of x is: x = 3.
Here, we have,
given that,
9+5x=24 is the equation:
Simplifying
9 + 5x = 24
Solving
9 + 5x = 24

0 + 5x = 24 + -9
5x = 24 + -9
Combine like terms: 24 + -9 = 15
5x = 15
Divide each side by '5'.
x = 3
Simplifying
x = 3
Hence, The solution is : in the equation 5x+9=24 the value of x is: x = 3.

Given the similar triangles shown in the diagram below :
A) set up an equation and solve for x
B) find the length of side AB
C ) find the side length of side AC
Answer:
a.) (x-3)(x-3) = 25 + (x-4)(x-4)
x^2 - 6x + 9 = 25 + x^2 - 8x + 16
-6x + 9 = -8x + 41
2x + 9 = 41
2x = 32
x = 16
b.) 16 - 4 = 12
AB = 12
c.) 16 - 3 = 13
AC = 13

suppose you are measuring peanut butter. begin with 1 1/2 c cold water in a container. after you add the peanut butter to the water, the water level reads 2 1/4 c.what is the volume of the peanut butter. explain.
Volume of the peanut butter is 3/4 c.
What is Subtraction?Subtraction can be done for any numbers or algebraic expressions. It is the process of taking out certain value from a given amount of number.
The process of subtraction can also be termed as finding difference.
Here is given the method to measure the peanut butter.
Volume of the cold water at the beginning = 1 1/2 c
= 3/2 c
Volume of the water after adding the peanut butter = 2 1/4 c
= 9/4 c
Volume of peanut butter = 9/4 c - 3/2 c
= (9/4) - (6/4)
= 3/4 c
Hence the volume of the peanut butter is 3/4 c.
