EXPLANATION
By the sum of interior angles of an hexagon theorem, we know that the sum of angles is equal to 720 degrees.
90 + x + (x+22) + 90 + x + (x+22) = 720
Removing the parentheses:
90 + x + x + 22 + 90 + x + x + 22 = 720
Adding like terms and numbers:
224 + 4x = 720
Subtracting 224 to both sides:
4x = 720 - 224
Subtracting numbers:
4x = 496
Dividing both sides by 4:
x= 496/4
Simplifying:
x = 124
Answers:
The sum of interior angles is 720 degrees.
x = 124
