Question

How do I find the value of x?

Answer 1

x = 70

Explanation:

Remark

There are 6 sides. The sum of the interior angles is (n - 2)*180. n in this case is 6.

(6 - 2 ) * 180 = 720

Equation

102 + 146 + 120 + 124 + 158 + x = 720 Combine like terms

Solution

x + 650 = 720 Subtract 650

x = 720 - 650 Combine

x = 70
