1. 2. Use the law of sines and/or law of cosines to solve the following triangle. SHOW ALL WORK! If no triangle exists, state so. If 2 triangles exist, then list all angles and sides for both triangles. Round to the measures given and include all units 3. A. B. C. 4. Use a complete sentence to list all the types of triangles by their angles. Then use sentences to describe triangles by their angles that are not RIGHT triangles. Draw pictures of these triangles. D. If m < B = 42.5°, m <C = 69.7°, a = 20.2 cm An obtuse triangle is an oblique triangle. m<A = True or False? (Write out the COMPLETE word that you choose for each answer). The Law of Sines applies only to right triangles. If you are given the measures of two sides and any angle, there is a unique solution for the triangle If you are given two sides that have the same length in a triangle, then there can be at most one triangle. b= A. B. C. D. The distance between an aircraft carrier and a Navy destroyer in the Pacific Ocean is 12,620 feet. The angle of elevation from the destroyer to a helicopter flying between the ships is 69.29* while the angle of elevation from the aircraft carrier to the helicopter is 56.39⁰. Use this information to find the distance, to the nearest foot, from the helicopter to the aircraft carrier. Solve the problem by using the law of sines and/or the law of cosines. Draw a picture to represent the problem. Show all work and write your answer on the line provided.
