**How do you find the length of a side in trigonometry?**

Trigonometry involves calculating angles and sides in triangles. The three trigonometric ratios can be used to calculate the length of a side in a right-angled triangle. Calculate the length AB. Give the answer to one decimal place. Label the sides of the triangle \ (o\), \ (a\) and \ (h\). Next choose the correct ratio from \ (s^o_h~c^a_h~t^o_a\).

**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.
