If you are given a triangle with measurements of two angles missing, how do you find those measures? For example, I have a right triangle. So, I know the measure of angle C is 90 degrees. I know that side A is 12mm, side B is 16mm, and side C is 20mm. How do I find the measures of angle A and angle B? The triangle is set up so that the 90 degree angle (angle C) is at the top. Straight across is the hypotenuse (side C; 20 mm). Angle A is on the lower right hand side (?), and in between angle A and angle C is the 16 mm side (side B). Angle B (?) is in the lower left hand corner, and in between angle B and angle C is the 12mm side (side A). And as I've already stated, in between angle A and angle B is side C (hypotenuse; 20mm). I hope this makes sense. It's hard to explain without being able to show you a picture. I know you have to use the Sin, Tan, and Cos stuff, but if anyone could explain to me how to find the measures of angle A and angle B, that would be great. Thanks so much!
