Some Info I know so far is tan(a)=5/2, tan(b)=1/2 and tan(b+gamma)=3/2

You have told me that

tan(alpha)=5/2,

tan(beta)=1/2

tan(beta+gamma)=3/2

so far so good:)

Here is some formulas that you may be able to make use of:

See what you can do with that.

I got it, Melody!, TYSM

that is excellent
