## Frequently Asked Questions

How do you use trigonometry to find the side lengths?

The trig ratios can be used to find lots of information, and one of their main purposes is to help solve triangles. To solve a triangle means to find the length of all the sides and the measure of all the angles. This lesson will cover how to use trig ratios to find the side lengths of a triangle.

How to solve a triangle with trigonometry?

To solve a triangle means to find the length of all the sides and the measure of all the angles. This lesson will cover how to use trig ratios to find the side lengths of a triangle. 1. Choose which trig ratio to use.

How to find an unknown side length in a right triangle?

Learn how to use trig functions to find an unknown side length in a right triangle. We can use trig ratios to find unknown sides in right triangles. Let's look at an example. Given , find . Step 1: Determine which trigonometric ratio to use. Let's focus on angle since that is the angle that is explicitly given in the diagram.

What is the trigonometric ratio that contains both sides?

Note that we are given the length of the , and we are asked to find the length of the side angle . The trigonometric ratio that contains both of those sides is the sine. [I'd like to review the trig ratios.]
