please help ASAP! will give brainlist!

A. Y = 7
B. Y = 32
C. Y cannot be determined with the information given
D. Y = 4

Answer 1

If you know that the triangles are congruent then you can use CPCTC to show that 21=3x and 60=4x+8y

We can easily divide 21 by 3 which gives us x=7 so we can multiply 4 times 7 and then subtract that from 60 which gives us 32=8y and then when you solve from there you get y=4

Answer 2

I think this is the Answer is y=4
