Question

The four-sided figure shown in the figure below consists of two triangles having a common side a. The law of cosines for the top triangle states that \(a^2 = b_1^2 + c_1^2 - 2b_1c_1 \cos A_1\). A similar equation can be written for the bottom triangle. Write a matlab code to compute the length of side c2 if you are given the lengths of sides b1, b2, and c1 and the angles A1 and A2 in degrees. Test your script using the following values: b1 = 180 m, b2 = 165 m, c1= 115 m, A1 = 120°, and A2 = 100°.

The four-sided figure shown in the figure below consists of two triangles having a common side a. The law of cosines for the top triangle states that $$a^2 = b^2 + c^2 - 2bc \cos A_1$$. A similar equation can be written for the bottom triangle. Write a matlab code to compute the length of side c2 if you are given the lengths of sides b1, b2, and c1 and the angles A1 and A2 in degrees. Test your script using the following values: b1 = 180 m, b2 = 165 m, c1= 115 m, A1 = 120°, and A2 = 100°.
