Answer:
<2 =67
Step-by-step explanation:
A linear pair adds to 180 degrees
<1 + <2 =180
113+ <2 = 180
<2 = 180-113
<2 =67
Alright, lets get started.
If the polygon measures 45 degree exterior angle and we are asked to find number of sides, there is a formula for that.
= value of exterior angle
Where n is number of sides of ploygon

Multiplying n into both sides


Now divide 45 in both sides

n = 8
Means number of sides of polygon is 8, hence its Octagon. Answer
Now we have given 45 exterior angle hence interior angle would be
180 - 45 = 135°
So, sum of all interior angles would be = number of sides * interior angle
sum of all interior angles would be = 
Hence sum of all interior angles would be 1080°. Answer

to find the area of compound shapes, you break them apart and find each shapes area then add it together.
to find the area of a square, use A=l * w
to find the area of a triangle, use, A= 1/2 b * h
Answer:
29 times
Step-by-step explanation:
We can find this answer by dividing 87 by 3
87/3 = 29
We can prove this by multiplying 29 times 3 which gives us 87
