Answer:

72

Explanation:

5a = 540 [ all interior angles r equal to 540 as "(n-2)x 180 (Interior ____________________________________________angle poperty )]

a= 540/5 = 108 (one interior angle)

x + a = 180 (linear pair)

x= 180 - a

x = 180 - 108 = 72

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Another way ::

Sum of Exterior angle = 360 (exterior angle property)

One exterior angle = x = 360 / 5 = 72 ( 360 by the number of sides )

I hope im right!1 Sorry if im wrong :((
