Using the Tangent Function

Hypotenuse - the side across from the 90 degree symbol (the little square)

Opposite - The leg on the opposite side of the triangle from the angle

Adjacent - The leg that is next to (adjacent to) the angle.

Equation

Tangent is abbreviated to “tan” in math, and on the calculator.

The Tangent Function of a specific angle is the ratio of the length of the side that is opposite to that angle to the length of the side that is adjacent to that angle.
