Question

if an interior angle in a polygon is (8x+12)and extrior angle is (3x-8)find the no of sides in polygon​

Answer 1

Answer:

9

Step-by-step explanation:

8x+12+3x-8=180

11x+4=180

11×=180-4=176

x=180÷11=16

measure of exterior angle=40

total measure of exterior angle=360

hence,number of sides in the polygon=360÷40=9
