Trig ratios can be used to find missing angles and sides of a right triangle. When you have a right triangle and you to find a missing side length or angle you can follow these steps.

Step1.Decide which trig ratio you should use (Sine,Cosine,or Tangent) based on the information you are given.

Step 2. Set the problem up with the angle and the ratio of the two sides.

Step 3. Calculate to change the ratio to a decimal

Step 4. Use a cross product

Step . Solve

Example problem worked out equals.

If you have a right triangle with an angle of 50 degrees and an opposite side of 5 units, what is the hypotenuse length?
