Area of a Triangle Given 2 Sides and an Angle

Given two sides and an angle, this formula is the most appropriate to use. The two sides given are adjacent to the given angle as you can see.

Formula

If you are given side a, and side b, and an angle C then it is possible to calculate the area A.

Calculator Solver

This calculator will find out the area providing you have two sides and an angle. The angle is in degrees.

Formula Rearranged

By transposing the standard formula you can find out the values of the angle C, and length a, and length b. In the first formula above you can calculate the angle C, given the area A, and lengths a, and b.
