Question

How do I find the value of x?

Answer 1

Answer:

x = 70

Step-by-step 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
