Answer:

Two angles measure 123°.

The other two angles measure 57°.

Explanation:

I assume the quadrilateral is a parallelogram.

In a parallelogram, opposite angles are congruent.

Consecutive angles are supplementary.

Supplementary angles 2x - 5 and 180.

2x - 5 + 123 = 180

2x = 62

x = 31

Congruent angles 3y and 123

3y = 123

y = 41

3y = 3(41) = 123

2x - 5 = 2(31) - 5 = 57

Two angles measure 123°.

The other two angles measure 57°.
