Use the Law of Cosines. Find length x. 19 70° C. B 18​

1. a right triangle is graphed on a coordinate plane. find the length of the hypotenuse. round your answer to the nearest tenth. 2. use the angle relationship in the figure below to solve for the value of x. assume that lines a and b are parallel and line c is a transversal.

The figures below are made out of circles, semicircles, quarter circles, and a square. find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations).

What are the solutions of the system? solve by graphing. y = -x^2 - 3x + 2 y = -2x + 2
