Answer: x = 17
y = 102 degrees
Step-by-step explanation:
The opposite sides of a parallelogram are equal and parallel. From the information given,
opposite side of x is 17. Thus,
x = 17
Also, the sum of the consecutive angles are in a parallelogram is 180 degrees. 78 and y are consecutive angles. This means that
78 + y = 180
y = 180 - 78
y = 102 degrees
