Question 843774
 If a right triangle has angles ab at 29, bc at 21 and ac at 20. 
Draw the picture.
You have a right triangle with:
hypotenuse = 29 = ab
side opposite b = ac = 20
side adjacent to b = bc = 21
---
How do you find the values of sine, cosine, and tangent of angle b?
sin(b) = opp/hyp = 20/29
cos(b) = adj/hyp = 21/29
tan(b) = opp/adj = 20/21
