Question

find the no.of sides of a polygon, if the sum of its interior angle is 3060°.​

Answer 1

So the sum of the angle measures of a convex polygon with n sides is 180%28n-2%29.

Your angle sum is 3060 degrees; 3060%2F180+=+17; so 17 is (n-2), which means the polygon has 19 sides.

Answer 2

Answer:

19 sides

Step-by-step explanation:

For finding the sides

(n-2) 180 = 3060°

(n-2)= 3060/180

(n-2)=  17

n = 17 + 2

n= 19 sides

Note that (n) means the number of sides
