Navigators locate an object by measuring its location clockwise direction from due north. The measure of the angle is called the bearing. Suppose a lighthouse's bearing is 150° from an island. Be sure to show and explain all work for each part. Part 1: Find the angle represented by the lighthouse on the unit circle. Part 2: Determine the exact ordered pair associated with the lighthouse on the unit circle. Part 3: Find the exact sine, cosine, and tangent of the angle on the unit circle.
