Question

find
the number of sides of the polygon whose sum of interior angle is given
below:

900​

Answer 1

Answer:

Number of sides = 7

Step-by-step explanation:

Sum of interior angles of a polygon is given by the formula, (n - 2)×180°

where n is the number of sides.

Therefore,

900°= (n - 2)×180°

5 = n - 2

n = 7

There are 7 sides.
