Have you studied right triangle trig?

anonymous · Answer

yes but I'm a little confused

directrix · Answer

Okay. Look at the chart and see which trig function of angle A would be the ratio of the opposite leg to the adjacent leg. The hypotenuse is not a leg.

directrix · Answer

The tangent of angle A is the length of the opposite leg over the adjacent leg.

directrix · Answer

In your problem, tan(A) = (BC)/(AC)
Look at the diagram you posted.
How long is side BC?
