# Trigonometric Ratios in Right Triangles

**How to effectively deal with bots on your site? The best protection against click fraud.**

In this video I will explain **the trigonometric ratios in the right triangle. **

It is also related to mathematics for its** trigonometric ratios.**

They can only be applied to **right triangles** since they follow some criteria by which they have to have legs and hypotenuse.

The sine, cosine, and tangent can be used to find the **angles** and measurements of **sides** unknown.

- The
**hypotenuse**, is the side opposite the 90º angle and is the longest side of a right triangle. - The
**Hick opposite**, is the side opposite the opposite angle considered. - The
**adjacent leg**, is the leg that forms the acute angle considered.

**Breast** of an angle is the quotient between the length of the opposite leg and the hypotenuse.

* Sine = opposite / hypotenuse*

The cosine of an angle is the quotient between the length of the contiguous or adjacent leg divided by the hypotenuse.

* Cosine = adjacent / hypotenuse*

**Tangent** of an angle is the quotient between the length of the opposite leg divided by that of the adjacent leg.

*Tangent = opposite / adjacent*

In the video you will see visual and graphic examples of **the trigonometric ratios in the right triangle.** Also, if you want to practice what you learned in today's class, you can do the **printable exercises with their solutions** that I have left you on the web.
