Question 843774: If a right triangle has angles ab at 29, bc at 21 and ac at 20. How do you find the values of sine, cosine, and tangent of angle b?

You can put this solution on YOUR website! 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
