How Do You Use Sin, Cos or Tan to Calculate Lengths in a Right Triangle?

This video explains how to find the length of a side in a right triangle using the sin, cos or tan formulas. Insert the known variables and solve the equation. 

The sine of an angle is defined as the length of the opposite side divided by the length of the hypotenuse.

The cosine of an angle is defined as the length of the adjacent side divided by the length of the hypotenuse.

The tangent of an angle is defined as the length of the opposite side divided by the adjacent side.

Given an acute angle in a right triangle, the opposite leg is across from the angle

Given an acute angle in a right triangle, the adjacent leg is a part of the angle
