## 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 do you find the missing side of a triangle?

Find the missing angle for each triangle. For each triangle, use the GIVEN acute angle & side length to create a trig ratio (sine, cosine, or tangent) to solve for a missing side of your choice. Each trig ratio must be used once during your lesson.

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.
