Hi Forum!

I have a question

We are to find the x coordinate of P to maximize abp

a(1,2) [use your imagination here, the graph is not right hahaha]

b(-1,1)

c(-1,0)

d(1,0)

Now, if we consider t as the x coordinate of P, we have:

Tan(A)=2/1-t

Tan(B)=1/1+t

If we have to find Tan(C), how should we do it?

A+B+C=180

C=180-A-B

Where do we go from there?

We know that tan(180) is 0, but how are we going to use it?

Thanks.
