Question

the sonar system then detects a sunken ship 1500 meters ahead, with an angle of elevation of 19° to the highest part of the sunken ship. how many meters must the submarine rise to pass over the sunken ship?

Answer 1

Explanation:

Tan Φ = opposite leg / adjacent leg

tan 19 = height / 1500

1500 * tan 19 = height = 516 m <==== must rise this much
