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
