Step-by-step explanation:
if half the balls are even then presumably another will be
There are 2 ways to do this:
1) Transform tan into terms of sin.
where
Substituting back in gives:
2) Use a right triangle.
sin = opp/hyp --> opp = 2, hyp = 5
Use Pythagorean theorem to solve for adjacent side.
tan = opp/adj
