There are several ways to find the angles in a triangle, depending on what is given: Given three triangle sides. Use the formulas transformed from the law of cosines: \cos (\alpha)=\frac {b^2+c^2-a^2} {2bc} cos(α) = 2bcb2 + c2 −a2. So: \alpha= \mathrm {arccos}\left (\frac {b^2+c^2-a^2} {2bc}\right) α = arccos (2bcb2 + c2 − a2)

Although side a and angle A are being used, any of the sides and their respective opposite angles can be used in the formula. This free triangle calculator computes the edges, angles, area, height, perimeter, median, as well as other values and a diagram of the resulting triangle.
Right triangle calculator to compute side length, angle, height, area, and perimeter of a right triangle given any 2 values. It gives the calculation steps.
Method Three: Using One Leg and One Angle. If you know the length of one leg and the value of an adjacent angle, then you can use the tangent function to find the area. Given the value of leg a and angle β, find the area using the following formula: A = a² × tan(β) / 2. Given the value of leg b and angle α, find the area using the ...
