## Frequently Asked Questions

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?
