Example 3

A sonar operator on an anchored cruiser detects a pod of dolphins feeding at a depth of about 255 meters directly below. If the cruiser travels 450 meters west and the dolphins remain at the same depth to feed, what is the angle of depression, [math]x[/math], from the cruiser to the pod? What is the distance, [math]y[/math], between the cruiser and the pod? Round your answers to the nearest whole number.
