So I really don't know how to do this, and I am very confused as to how and I've tried a lot of different solutions. I just can't figure out how to calculate the answer. Can someone please show me the steps to solve this? Thanks

a) Tan(alpha + beta)

b) tan(y)

c) Tan(alpha + beta + y)

 

So basically in the beginning I tried to find comboes to make it a right triangle but it just wouldn't work. I was able to find tan(a), tan(y+b), and tan(b).

(a) tan (alpha + beta) = 3/2

(b) tan y = 7/8

(c) tan (alpha + beta + y) = -8/3
