Question

The interior angles formed by the sides of a quadrilateral have measures that sum to 360°.

Answer 1

The sum is 360 degrees, which means
360 = 124 + 124 + 2x + 2x
360 = 248 + 4x
-4x = 248 - 360
-4x = -112
x = 28
Check:
124 + 124 + 2(28) + 2(28) =
360
Your answer is x = 28

Answer 2

X=28
Because the sum is 360° so 124 +124=248
So 360-248=112
Then 112÷4=28
So 28×2=56 28×2 =56
56+56=112
