2x+2x+124+124 = 360
4x+248 = 360
4x = 360 - 248
4x = 112
x = 112/4
x = 28

answer x = 28

Let


angle 1=2x°


angle 2=2x°


angle 3=124°


angle 4=124°


we know that

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

so


angle 1+angle 2+angle 3+angle 4=360°


2x+2x+124+124=360\\ 4x+248=360\\ 4x=112\\ x=28degrees

therefore


the answer is


x=28degrees
