Question

A polygon has n sides . Three of its exterior angles are 36,55,65 degree while the remaining (n-3)exterior angles are each equal to 8.5 degree .find n?

Answer 1

Answer:

n=27

Step-by-step explanation:

we know that sum of exterior angles of a polygon is 360°

thus,

8.5*(n-3) + 36+55+65 = 360

8.5(n-3) + 156 = 360

8.5*(n-3) = 360-156

8.5*(n-3) = 204

n-3 = 204/8.5

n-3 = 24

n = 24+3

n= 27
