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°

$angle 1+angle 2+angle 3+angle 4=360$ °

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

therefore

the answer is

$x=28degrees$
