## Frequently Asked Questions

How do you find the side length of a triangle?

Given a right angle triangle, the method for finding an unknown side length, can be summarized in three steps : Step 1: Label the side lengths, relative to the given interior (acute) angle, using "A", "O" and "H" (label both the given side length as well as the one you're trying to find).

How to solve for a side in right triangles with trigonometry?

Solving for a side in right triangles with trigonometry Let's look at an example.. Given , find . Solution. Step 1: Determine which trigonometric ratio to use. Let's focus on angle since that is the angle that is... Now let's try some practice problems.. Given , find . Round your answer to the ...

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.]

How do you find the unknown sides of 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. Note that we are given the length of the , and we are asked to find the length of the side angle .
