How Do You Find the Tangent of an Angle in a Right Triangle?

What's a trigonometric ratio? It is a ratio between two sides of a right triangle. In this problem, find tangent(A) in the given right triangle. Use the ratio of the opposite side divided by the adjacent side to find tan(A). The instructor draws a diagram and labels all the sides and angles. She then explains how to apply the formula to find tan(A).
