Question

If ΔABE ~ ΔACD, find the value of y.

Answer 1

A. y = -1
B. y = 1
C. y = 2.4
D. y = 6

Answer 2

Since they are both similar the ratio can be taken by the known lengths. 10 is similar to 6. so y+4 is similar to y in the same ratio.

There are no negative distances so A) is out of the choices.

the ratio between y+4 and y is .6

Answer 3

thank you (:

Answer 4

6 + 4 and 6 would be the same ratio as 10 and 6 which matches the other two known lengths (wow what a coincidence)
