Find cos , given that cos θ = – and θ terminates in 180° < θ < 270°.

Two points A and B are on opposite sides of a building. A surveyor selects a third point C to place a transit. Point C is 46 feet from point A and 64 feet from point B. The angle ACB is 50°. How far apart are points A and B?

A room in the shape of a triangle has sides of length 7 yd, 8 yd, and 11 yd. If carpeting costs $19.50 a square yard and padding costs $3.25 a square yard, how much to the nearest dollar will it cost to carpet the room, assuming that there is no waste?

Find the area of the triangle. If necessary, round the answer to two decimal places.A = 40°, b = 11, c = 5
