Answer:
x = 9 , y = 18
Explanation:
(5x - 27)° and 2x are alternate angles and are congruent (equal) , then
5x - 27 = 2x ( subtract 2x from both sides )
3x - 27 = 0 ( add 27 to both sides )
3x = 27 ( divide both sides by 3 )
x = 9
Then
2x = 2 × 9 = 18
y and 2x are corresponding angles and are congruent , so
y = 2x = 18
