Given the two similar triangles, find y.

a= y = 4

b= y = 5

c= y = 6

d= y = 8

giving brainlist to whoever answers with work.

The correct answer is B. y = 5

Step-by-step explanation:

Let's recall that two are triangles are similar when its side lengths are proportional. That is in our case, if Δ ABC is similar to Δ DEF , then the following equation holds:  

EF/BC = DF/AC

Replacing with the real values:

6/12 = y/10

Cross multiplication:

12 * y = 10 * 6

12y = 60

y = 60/12

y = 5

The correct answer is B. y = 5

answer: 1 and 3

step-by-step explanation:

1. minimum

2. 6400

3. eight

hope this !
