1 point
x = 11.25 and y = 18.75
x = 12.25 and y = 18.75
x = 11.25 and y = 16.45
x = 14.28 and y = 17.95
x = 10.25 and y = 20.75

Answer 1

x = 11.25 and y = 18.75

Explanation:

ΔABD ≅ ΔBCD

⇒ 20 : 15 = 15 : x

⇒ 20/15 = 15/x

⇒ x = 15 × 15/20

⇒ x = 11.25

⇒ 25 : 20 = y : 15

⇒ 25/20 = y/15

⇒ y = 25/20 × 15

⇒ y = 18.75
