Given two vectors and the angle between them, which of the following concepts in trigonometry is useful to solve for the third side of the triangle? O Law of sines Double angle identities Pythagorean theorem O Law of cosines

In the next sets, you are given the magnitude and one component. There is an ambiguity in determining the vector, because you can only determine the absolute value of the other component and not its sign; therefore, there are two possibilities. In these tables, you must enter the absolute value of the component and provide two angles for the vector, the first one assuming the other component is positive and the other assuming the component is negative. You must also provide two angles for the antiparallel vector in the same order.
