Let's pratice the steps we learned in the last GeoGebra for finding a missing side of a triangle using a trigonometric ratio:
- Label the side you're trying to find with x.
- Use opposite, adjacent, or hypotenuse to label the side you know & the side you want to find.
- Choose the trig ratio that involves the two sides you just labeled.
- Set up an equation using the trig ratio you choose by filling in the angle and side length you know and x for the side you don't know (or if the unknown side is already labeled use that variable).
- Solve the equation.
Use a trigonometric ratio to find side b. Give the equation you used to solve as well as the answer to b.
Use a trigonometric ratio to find side AB. Give the equation you used to solve as well as the answer to AB.
Use a trigonometric ratio to find side c. Give the equation you used to solve as well as the answer to c.
