Answer:

x = 118

Step-by-step explanation:

Sum of angles of a regular pentagon = 540

=> 87 + 108 + 135 + 92 + x = 540

=> 422 + x = 540

=> x = 540 - 422

=> x = 118

Answer:

x = 118

Step-by-step 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 + 92 + 135 + 108 + 87 = 540 , that is

x + 422 = 540 ( subtract 422 from both sides )

x = 118
