Question

Solve for the value of x, using the properties of the parallelogram​

Answer 1

Explanation:
1. Angle x is opposite to the 75 degree angle => x = 75 degrees
Property : Opposite angles are congruent.

2. Angle 2x is consecutive to the 80 degree angle => x = (180-80)/2 = 50 degrees

Property : Consecutive angles are supplementary.
