Amy is up in the lighthouse tower looking out at the ship. She knows the lighthouse (BC) is 13 m tall.She measures the angle of depression to be 140How far (AC) out to sea is the ship from the base of the tower?Round to the nearest 2 decimal places. (Put the numbers only in the box, do not enter any units.)

The angle of depression from the top of a lighthouse to the base of a boat out at sea is 10°. If the lighthouse is at the edge of land and is 82 meters tall, approximately how far out at sea is the boat?

An observer in a lighthouse is 45 meters above the surface of the water. The observer sighted two ships due east. The angle of depression to ship A is 51 degrees and the angle of depression to ship B is 24 degrees. Which ship is closer to the base of the lighthouse?

A boat is heading towards a lighthouse, whose beacon-light is 140 feet above the water. The boat’s crew measures the angle of elevation to the beacon, 10degrees ∘ . What is the ship’s horizontal distance from the lighthouse (and the shore)? Round your answer to the nearest tenth of a foot if necessary.

Martha observed a boat from the top of a 74.5 m cliff. She noted that the angle of depression to the boat was 22.70How far is the boat from the base of the cliff ?Round to the nearest 2 decimal places. (Put the numbers only in the box, do not enter any units.)

A yacht is anchored 90 feet offshore from the base of a lighthouse.  The angle of elevation from the boat to the top of the lighthouse is 26 degrees.  The distance between the yacht and the top of the lighthouse is about 100 feet.  Calculate the height of the lighthouse? (Round your answer to the nearest whole number.)
