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
