I can help with the second part. The Sine of an angle is going to be the same as the cosine of that angle's complement. Picture a right triangle. The sum of the angles in a triangle is 180 and one of those is a right angle, leaving the other 2 to be 90.

Well does anyone know something regarding the 1st part, I have to talk to my geometry teacher in a little while and I know she's gonna ask that question for sure...
