x = 60
y = 30
Step-by-step explanation:
Adjacent angles are supplementary.
(5x -180) +x = 180
6x = 360 . . . . . . . . . . add 180, collect terms
x = 60 . . . . . . . . divide by 6
Opposite angles are congruent.
2y = 60 . . . . . . 2y = x
y = 30 . . . . . . . .divide by 2
The value of x is 60; the value of y is 30.
