Explanation of Solution
Given information: If raindrops are falling toward Earth at a speed of 45 miles per hour and a horizontal wind is blowing at a speed of 20 miles per hour.
Calculation:
We have two sides of the triangle and want to find an angle. We use trig ratios. Since the sides we know are the opposite and adjacent, we use the arc tangent to find the angle.
