The interior angles formed by the sides of a quadrilateral have measures that sum to 360°.
Svetach [21]

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
