Question

Find the measure of the missing angle.

150
160

Answer 1

x = 50

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 5 angles and equate to 540

90 + 90 + 160 + x + 150 = 540

x + 490 = 540 ( subtract 490 from both sides )

x = 50
