Answer
yes it is correct
Step-by-step explanation:
Answer:
Part a) The measure of an exterior angle is 60°
Part b) The measure of an interior angle is 120°
Step-by-step explanation:
step 1
Find the value of x
we know that
A regular polygon has equal sides and equal interior angles
The sum of an interior angle plus an exterior angle must be equal to 180 degrees (supplementary angles)
so

solve for x


step 2
Find the measure of an exterior angle
2x
substitute the value of x

step 3
Find the measure of an interior angle
4x
substitute the value of x

In this problem the regular polygon is a hexagon
Answer:
long pieces 126 Short pieces 21
Step-by-step explanation:
18+18+18+18+18+18+18=126
3+3+3+3+3+3+3=21
hope this helped <3
