Answer:
x = 20
y = 19
Explanation:
(2x - 3)° + (3x - 7)° = 90° (complementary angles)
(2x - 3 + 3x - 7)° = 90°
(5x - 10)° = 90°
5x - 10 = 90
5x = 90 + 10
5x = 100
x = 100/5
x = 20
2y - 1 = 2x - 3 ( vertical angles)
2y = 2x - 3 + 1
2y = 2x - 2
2y = 2*20 - 2 (plug x = 20)
2y = 40 - 2
2y = 38
y = 38/2
y = 19
