•what is the sum of the measures of the exterior angles of an octagon? 360

-answer to the picture above-
what is the value of X? 84

•what is the measure of an exterior angle of a regular pentagon? 72

sorry i don’t have the explanations.

Answer 1

Answer:

84°

Step-by-step explanation:

The value of x in the given pentagon can be solved as follows:

Sum of interior angles of a polygon is given as (n - 2)180

Sum of pentagon = (5 - 2)180 = 3(180) = 540°

Therefore all the interior angles of the given pentagon in the picture = 540°

Thus:

x + 131 + 108 + 107 + 110 = 540

x + 456 = 540

Subtract 456 from both sides

x = 540 - 456

x = 84°
