Answer:
1) Find the number of sides if the measure of an interior angle is 177o in a regular polygon. Remember that the sum of the angles is (n-2)*180. 2) Find the measure of each interior angle if a regular polygon has 15 sides. Remember that the sum of the angles is (n-2)*180.
Step-by-step explanation:
Answer:
Let the number of sides be x.
One interior angle is 177°
One exterior angle is 180-177 (linear pair)
= 3°
Exterior angle × Number of sides = 360
3*x = 360
x = 360/3
x = 120
Therefore, the polygon has 120 sides.
