Use pythagorean theorem to get your third side, then use triangular trig ratios to get the trig functions... like sin(theta)=opp/hyp, cos(theta)=adj/hyp, etc...

There is a nice little short cut too... once you find sin, cos, and tan... csc, sec, and cot are the reciprocals.

That is not what I got. What did you get for the missing side?

eek!\[c ^{2}=a ^{2}+b ^{2}\]where c is the hypotenuse. You have c and a... solve for b\[b=\sqrt{c ^{2}a ^{2}}\]

It comes out nice... not irrational. What do you get for the missing side now?

Now, all of those trig functions have angle A in them... so you are looking at the triangle from that corner. If that's the case, then 9 is your adjacent side, 12 is your opposite side, and 15 is the hypotenuse. So what is sin A=opp/hyp?

Yes! Now cos A=adj/hyp... which is?
