Question 2: the measure of an exterior angle of a regular polygon is given below. find the measure of an interior angle. then find the number of sides. 24 what is the measure of an interior angle? how many sides does the polygon have? question 1: what are ed and fd in the figure to the right? ed= fd=

Question 1:
What are ED and FD in the figure to the right?

ED = 20
FD = 2 x 20 = 40

Question 2:
The measure of an exterior angle of a regular polygon is given below. Find the measure of an interior angle. Then find the number of sides.
24

What is the measure of an interior angle?
(n-2) x 180° / n
= (15-2) x 180 / 15
= 13 x 180 / 15
= 2340 / 15
= 156

answer
156 degrees

How many sides does the polygon have?
360 / 24 = 15

answer
15 sides
