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:

  1. First, determine the opposite side length. 
    • The opposite side length is given as: 21.
  2. Next, determine the adjacent side length. 
    • The adjacent side length is provided as: 16.
  3. 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 = ?
