Homework 8 law of cosines.

The triangle shape has three angles and three sides. We can find the unknown sides and the angles of the triangle by using the law of cosines and the law of sines. The formula for the law of cosines is {eq}\displaystyle c^{2}=a^{2}+b^{2}-2ab \cos (C) {/eq}.View Answer. Find all angles, then find the area if the three sides measure 3, 6 and 4 in a triangle. View Answer. Solve the triangle. a = 8.5 m, b = 6.1 m, C = 40 degrees. View Answer. Find different solution (s) to the triangle problem, if it exists. a = 10, b = 12, c = 16. View Answer.Objective. Students will practice deciding when to apply the law of cosines vs the law of sines to calculate the side length of a triangle and to calculate the measure of an angle. The second part of the sheet focuses on problems that require using the formulas more than once (law of cosines to get side, then law of sides to get angle etc..)
