Problem

27) An airplane is flying at a height of 2 miles above the ground. The distance along the ground from the airplane to the airport is 5 miles. What is the angle of depression from the airplane to the airport?

Solution

Step 1 :Given: opposite = 2, adjacent = 5

Step 2 :Calculate angle: \( \arctan(\frac{opposite}{adjacent}) \)

Step 3 :Plug in values: \( \arctan(\frac{2}{5}) \)

Step 4 :Calculate: \( \boxed{21.8} \) degrees
