Those to angles are equal to each other so set the angles equal and solve for x:
6x - 3 = 2x + 13
6x + (-3 + 3) = 2x + (13 + 3)
6x = 2x + 16
6x - 2x = (2x - 2x) + 16
4x = 16
4x/4 = 16/4
x = 4
Hope this helped!

Answer:
Step-by-step explanation:
One property of parallelograms is that opposite angles are congruent (there is a detailed proof for this, but it is very long).
So, 6x - 3 = 2x + 13.
Isolate x: 4x = 16
Divide: x = 4
