Question

What is the value of x

Answer 1

x = 70

Explanation:

the sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

here n = 5 , then

sum = 180° × 3 = 540°

sum the interior angles and equate to 540

x + 160 + 110 + 105 + 95 = 540

x + 470 = 540 ( subtract 470 from both sides )

x = 70
