Answer:

x = 8, y = 29

Step-by-step explanation:

5x + 9 and 4x + 17 are corresponding angles and congruent, so

5x + 9 = 4x + 17 ( subtract 4x from both sides )

x + 9 = 17 ( subtract 9 from both sides )

x = 8

-------------------------------------------------------

y + 20 and 5x + 9 are alternate angles and congruent, so

y + 20 = 5x + 9 = 5(8) + 9 = 40 + 9 = 49 ( subtract 20 from both sides )

y = 29
