Find the value of X. Help Me Please

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
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
