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

Two sides and an angle are given. Determine the number of triangles the given information results in. For triangle ABC, if a = 10, b = 12, and B = 51°, the following is true.

An airplane is sighted at the same time by two ground observers who are 4 miles apart and both directly west of the airplane. They report the angles of elevation as 12° and 21°. How high is the airplane?

In triangle ABC, if a = 12, b = 15, and c = 17, find the measure of the largest angle.

Two sides and an angle are given. Determine the number of triangles the given information results in. For triangle ABC, if a = 8, b = 10, and B = 52°, the following is true.

Two sides and an angle are given. Determine the number of triangles the given information results in. For triangle ABC, if a = 9, b = 11, and B = 48°, the following is true.

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 45 feet from point A and 75 feet from point B. The angle ACB is 59°. How far apart are points A and B?

In triangle ABC, if a = 9, b = 16, and c = 18, find the measure of the largest angle.

Solve the right triangle using the information given. Round answers to two decimal places, if necessary.a = 8, b = 5; Find c and β.
