Answer 1

Find the number of sides of a regular polygon if each of its interior angle is 168

pls answer fast and explain please fast

Answer 2

Answer:

30 sides

Step-by-step explanation:

Each interior angle = 180(n-2)/n (where n is number of sides)

Each interior angle = 168 (Given)

Number of sides -

168 = 180 (n-2)/n

168 = 180n - 360 /n

168n = 180n - 360

360 = 180n - 168n

360 = 12n

360/12 = n

n = 30
