Question

Find the no. Of sides of a regular polygon if each of its interior angle is 168

Answer 1

Answer:

30 sides

Step-by-step explanation:

let ext. angle of side be x

168 + x = 180

x = 180-168 = 12

As we know, sum of ext. angles = 360

As the figure is regular,

360 = (no. of sides) x 12

(no. of sides) = 360/12 = 30
