Give an example of a non-right triangle in which the Law of Sines would be appropriate to solve the triangle and an example of second non-right triangle in which the Law of Cosines would be appropriate to solve the triangle. Explain.
What will be an ideal response?
Law of Sines example should be a triangle with the measure of two sides and an angle opposite one of them or the measure of at least one side and any two angles given.
Law of Cosines example should be a triangle with the measure of all three sides or the
measure of two sides and their included angle given.
