WebApr 17, 2024 · $\begingroup$ You can just revert the vectors according to the need. $$$$ 1. $\vec X$ and $\vec Z$ to get $\angle A\\$ 2. $\vec Y$ and $- \vec X$ to get $\angle B\\$ 3. $-\vec Y$ and $- \vec Z$ to get $\angle C$ (in this example it's anyways 0) $$$$ So, first draw a rough triangle after selecting your vectors, then revert them according to the ... 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.
