Sum of interior and exterior angle is 180 so
Interior angle =180−72=108
Now we need to find the no of sides of the polygon= n We know that interior angle of n-sides is given by
(n−2)×180n
We have
(n−2)×180=108n
or
180n−360=108n
or
72n=360
n=5 sides so there are 5 angles each of 108 degrees Sum of the interior angles=108+108+108+108+108=540.....
<span>To find the measure of each exterior angle of a regular polygon, you just divide 360 degrees by the number of sides.

Kerion will take 1.5 hours to make 9 necklaces.
Step-by-step explanation:
Given,
12 necklaces are made in 2 hours.
We will find unit rate in terms of necklaces.
12 necklaces = 2 hours
1 necklace =
1 necklace =
For 9 necklaces, we will multiply 9 with unit rate
9 necklaces =
9 necklaces = 1.5 hours
Kerion will take 1.5 hours to make 9 necklaces.

In this situation I would use cosine to find m∠G.
Cosine = Adjacent side ÷ Hypotenuse
RG being the adjacent side and TG being the hypotenuse, you would set up the equation like this
cos(g) = 8/17
then solve
cos(g) = 0.47058
simplify
g = cos^-1(0.47058)
and you get
m∠G = 61.9°
So your answer would be 62°
