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
