1. A radar operator on a ship discovers a large sunken vessel lying parallel to the ocean surface, 150 m  directly below the ship. The length of the vessel is a clue to which wreck has been found. The radar  operator measures the angles of depression to the front and back of the sunken vessel to be 52° and 70°.  How long, to the nearest tenth of a meter, is the sunken vessel.

 

 

2. A radar operator on a ship discovers a large sunken vessel lying parallel to the ocean surface, 165 m

directly below the ship. The length of the vessel is a clue to which wreck has been found. The radar

operator measures the angles of depression to the front and back of the sunken vessel to be 40° and 62°.

How long, to the nearest tenth of a meter, is the sunken vessel

 

3. In ΔTUV, t = 6.0 m, u = 7.6 m, and v = 8.0 m.

Solve the triangle. Round angles to the nearest degree and sides

to the nearest tenth of a metre. Show your work
