Objective Solve problems involving angles of elevation and angles of depression.

An angle of elevation is the angle formed by a horizontal line and a line of sight to a point above the line. An angle of depression is the angle formed by a horizontal line and a line of sight to a point below the line. Read and complete the examples 1 & 2 on pages 343 – 344 of the core book.

Honors Example 3: Shipping Application An observer in a lighthouse is 69 ft above the water. He sights two boats in the water directly in front of him. The angle of depression to the nearest boat is 48º. The angle of depression to the other boat is 22º. What is the distance between the two boats? Round to the nearest foot.
