Calculate triangle sides using angles
WebFeb 16, 2024 · After re-arranging. beta = acos ( ( a^2 + b^2 - c^2 ) / (2ab) ) In trigonometry, the law of cosines (also known as the cosine formula or cosine rule) relates the lengths of the sides of a triangle to the cosine of one of its angles. First, calculate the length of all the sides. Then apply above formula to get all angles in radian. WebJan 27, 2015 · First you can bisect your angle given ($120$ degrees) to $60$ degrees. Then you will notice that you will have formed two triangles that follow the $30$-$60$-$90$ triangle format. $64$ is your hypotenuse …
