Emi is standing on a 50 m high bridge and sees two boats below. From her position, boat A has a bearing of 230°, and boat B has bearing of 120°. Emi estimates the angles of depression to be 38° and 35° for boat A and B, respectively. How far apart are the boats to the nearest tenth of a metre (one decimal place) ? S0 m 120° 230

Find the solution(s) for a triangle with B= 45.81°, C = 74.39°, a = 7.83cm Round your answers to 2 decimal places.

In the final seconds before the plane landed in the Hudson, the pilot slowed the plane.  While the plane slowed it climbed from 210 ft at 3:29.58 to 370 ft at 3:30.17. An elevation change of 160 ft over a distance of 2000 ft. What was the angle of ascent for the plane (e) as it slowed? Round your answer to the nearest hundredth (second decimal place).

A lighthouse-keeper 75 m above the ocean observes a ship sailing directly away from him. At 1 p.m. the angle of depression is 11° and 5 minutes later it is 4.5°. How fast is the ship travelling (in km/h)?
