Asap! will give brainlist! a. y = 7 b. y = 32 c. y cannot be determined with the information given d. y = 4

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

square root
