The four-sided figure shown in Figure P26 consists of two triangles hav- ing a common side a. The law of cosines for the top triangle states that a2 = b21 + c21 - 2b1c1 cos A1 and a similar equation can be written for the bottom triangle. Develop a procedure for computing 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. Write a script file to implement this procedure. Test your script using the following values:b1 ??180m,b2 ??165m,c1 ??115m,A1 ??120°andA2 ??100°. b2 B2 C2 a Figure P26 b1 A1 c C1 1
