# Acute angle calculator

Reference Angle Calculator To use the reference angle calculator, simply enter any angle into the angle box to find its reference angle, which is the acute angle that corresponds to the angle entered. The calculator automatically applies the

## How to Calculate Acute Angles

If the angle is between the given sides, you can directly use the law of cosines to find the unknown third side, and then use the formulas above to find the missing angles, e.g. given a,b,γ: calculate c = \sqrt {a^2 + b^2 - 2ab \times
