Find The Sum Of The Interior Angles Of The Following Polygon class=

Sagot :

Answer:

540° and x = 85°

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°

2

sum the interior angles and equate to 540°

x + 115° + 95° + 115° + 130° = 540°

x + 455° = 540° ( sum 455° from both sides )

x = 85°
