Enter the opposite side length and the adjacent side length into the Tangent Ratio Calculator. The calculator will evaluate and display the Tangent Ratio.

## Tangent Ratio Formula

The following formula is used to calculate the Tangent Ratio.

**TANR = O / A**

- Where TANR is the Tangent Ratio
- O is the opposite side length
- A is the adjacent side length

## How to Calculate Tangent Ratio?

The following example problems outline how to calculate Tangent Ratio.

Example Problem #1:

- First, determine the opposite side length.
- The opposite side length is given as: 21.

- Next, determine the adjacent side length.
- The adjacent side length is provided as: 16.

- Finally, calculate the Tangent Ratio using the equation above:

TANR = O / A

The values given above are inserted into the equation below and the solution is calculated:

TANR = 21 / 16 = 1.3125 ( )

Example Problem #2:** **

For this problem, the variables required are provided below:

opposite side length = 70

adjacent side length = 60

Test your knowledge using the equation and check your answer with the calculator above.

TANR = O / A** = ?**
