Question

The interior angle sum of a convex polygon is 900°. How many sides does the polygon have?

Answer 1

There are 7 sides

Explanation:

You can use the formula for finding the sum of the interior angles:

S=180(n−2) where n is the number of sides

If the sum is 900° we have:

180(n−2)=900

n−2=900/180

n−2=5

n=5+2=7

There are 7 sides.
