Question

the sum of the interior angles of a polygon is 900^{\circ}. how many sides does it have?

select one:
a. 9
b. 8
c. 5
d. 6
e. 7

what is the formula for finding the sum of the interior angles of a polygon with n sides?

select one:
a. 90(n-2)
b. 180n
c. 180(n-2)
d. 180(n+2)

how many sides does a regular polygon have if each interior angle measures 120^{\circ}?

select one:
a. 7
b. 6
c. 8
d. 5
e. 4

Explanation:

Solve for the number of sides given the interior angle sum
