Answer:

The number of sides is 7

Explanation:

Once the sum of interior angles is equal to 900º and the sum of interior angles is given by

$S=(n-2) \cdot 180\º, \text{ as }n \text{ being the number of sides}$

$900\º = (n-2) \cdot 180\º$

$(900\º)/(180\º) = (n-2)$

5 = (n-2)

5+2 = n-2+2

$\boxed{n=7}$
