__Pythagorean Theorem Questions__

1. Solve for x, rounded to the nearest tenth of a cm, where x is the hypotenuse and the lengths of the other two sides of a right-angled triangle are 13 cm and 16 cm.

2. Solve for x, rounded to the nearest tenth of a cm, where the hypotenuse of a right-angled triangle is 15 cm, one of the other sides is 11 cm, and the unknown third side length is x.

__Cosine Law__1. In Triangle GHI, solve for *h , *rounded to the nearest tenth of a cm, where *g*=19 cm, *i*= 14 cm, and H=111 degrees.

2. In Triangle MNP, solve for P to the nearest tenth of a degree, where M = 12 cm, N = 13 cm, and P = 14 cm.

A tutorial on the Cosine Law, as well as the answers to both of these questions, can be found at http://www.youtube.com/watch?v=EcK2QSDU01w&list=UUm-Z_cRxySqM3GkXMKmDPUg&index=1&feature=plcp. (The solution on the video uses the variable *x* within the solution, but it is not necessary to introduce this new variable).
