You mean 26 / 7 that equals 3.71428571
Answer:
Option B 
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
The perimeter of the figure is equal to sum the length of semicircle plus the length of three sides of a square
<u>Find the length of semicircle</u>
Remember that the circumference of semicircle is equal to

we have

substitute

The perimeter of the figure is equal to

Answer:
42
Step-by-step explanation:
So if the result of it is 31,
And it is 53 less you would add back 53
53 + 31 = 84
And it is twice a number so you divide by 2 (opposite of twice a number)
84/2 = 42
Let
x--------> the measure of the adjacent interior angle
y--------> the measure of an exterior angle at the vertex of a polygon
we know that
The measure of the adjacent interior angle and the measure of an exterior angle at the vertex of a polygon are supplementary angles
so
°
<u>Examples</u>
case 1)
<u>In a square</u>
°
so
°

In this case
The measure of an exterior angle at the vertex of a polygon equals the measure of the adjacent interior angle
case 2)
<u>an equilateral triangle</u>
°
so
°

In this case
The measure of an exterior angle at the vertex of a polygon is not equals the measure of the adjacent interior angle
therefore
<u>the answer is</u>
sometimes
5x+2<4×+4 this inequality will pay a childs price which is 2 $
