Answer :
Answer:
x = 5.5
Step-by-step explanation:
Since the shape is a parallelogram, the opposite angles are congruent. Angle A is opposite Angle Y so we can set their values equal to each other to solve for x:
3x + 10 = 2x + 15.5
Bring the variables to one side and the constants to the other:
x = 5.5
