Two strait lengths of wire are placed on the ground forming vertical angles. if the mesure of one of the angles formed is 72 what are the other three angles
The other three angles are 72° , 108° and 108°.
Two strait lengths of wire are placed on the ground forming vertical angles. The measure of one of the angles formed is 72° . We know that sum of all four angles will be 360°. We also know that the vertical angles are congruent. If the measure of one angle out of four angles is 72° and straight lines equal 180°. So, we need to subtract 72° from 180°.
180° - 72° = 108°
The other angle will be 108°. As the vertical angles are equal, so the four angles will be 72° , 72° , 108° and 108°.
The other three angles are 72° , 108° and 108°.

The correct answer 4+3w=5.
Variables in an equation are typically English alphabets and can have any real value that the equation is satisfied with. They also include coefficients and constants. In an equation, constants are the independent numbers for the variables, and coefficients are the numbers connected to the variables. Algebraic equations with orders equal to one or one are known as linear equations.
An analytical claim that two things are equal is known as an equation. Either a term or an expression are present in an equation. An equation is a statement of equality in mathematics that contains one or more variables.

The length of the rectangular shed is 2x^2 + 3x - 1 feet, and the width is x + 4 feet. Write polynomials that represent the perimeter and area. Calculate the perimeter and area if x = 10 feet. Include correct units of measure
Answer: You would replace the x's with 10.
New equations: 2 . 10^2 + 3 . 10 - 1 & 10 + 4
2 . 10^2 + 3 . 10 - 1 = 229
10 + 4= 14
Area = 3,206 feet
Perimeter = 486 feet

Write a recursive function called digit_count() that takes a positive integer as a parameter and returns the number of digits in the integer.
The count of integers is returned to the main function at the end of the function.
What are recursive functions?A recursive function is one that calls itself while running. The process may be repeated several times, with the result and the end of each iteration output. The function Count() below employs recursion to count from 1 to 10 using any number between 1 and 9.So,
The Python recursive function DigitCount(), which uses comments to explain each line, is as follows:
#This defines the function
def countdigits(n):
#If the integer is less than 10
if n< 10:
#Then the integer has 1 digit
return 1
#Otherwise,
else:
#Count the number of integers
return 1 + countDigits(n / 10)
At the end of the function, the count of integers is returned to the main function.
Therefore, the count of integers is returned to the main function at the end of the function.

Using complementary angles, the measure of angle 4 is of 39º.
What are complementary angles?If two angles A and B are complementary, the sum of their measures is of 90º.
In this problem, angles 3 and 4 are complementary, hence:
m<3 + m<4 = 90º.
Angles 1 and 3 are opposite by the same vertex, hence they are congruent and we can find x as follows:
m<1 = m<3
4x - 13 = 2x + 19.
2x = 32
x = 16.
The measure of angle 3 is given by:
m<3 = 2(16) + 19 = 51.
Hence the measure of angle 4 is found as follows:
m<3 + m<4 = 90º.
51 + m<4 = 90º.
m<4 = 39º.

The dimensions of rectangle B are 4.5 inches by 3 inches. So the correct option is the first one.
What are the possible dimensions of rectangle B?
We know that the dimensions of rectangle A are 6cm by 4cm, and rectangle B is similar to rectangle A, then the two rectangles have the same shape but different size.
Notice that the ratio between the dimensions of rectangle A is:
R = 6/4 = 3/2 = 1.5
Then, any other rectangle with the same ratio will be similar to rectangle A.
If we take the ratios for the options we get:
1) 4.5 in by 3 in:
R = 4.5/3 = 1.5
So yes, this rectangle is similar to rectangle A, then these can be the dimensions of rectangle B.
Then we conclude that the dimensions of rectangle B are 4.5 inches by 3 inches, and thus, the correct option is the first one.
