Worksheet law of cosines

Solve for all missing sides and angles in each triangle. Round to the nearest hundredth.

The law of cosines , commonly referred to as the cosine rule or the cosine formula in trigonometry, basically connects the length of the triangle to the cosines of one of its angles. It claims that we can determine the length of the third side of a triangle if we know the length of t he first two sides and the angle between them. On this website, we have prepared various law of cosines worksheets for extra practice.
