Question

A weather balloon is launched from the ground at a location that is 750 feet from a 65 foot royal palm tree. What is the minimal angle of elevation at which the balloon must take off in order to avoid hitting the tree? Assume that the balloon flies in a straight line and the angle of elevation stays constant. Round your answer to the nearest tenth. The minimal angle of elevation is.

Answer 1

Answer: 5°

Step-by-step explanation:

You can use a right triangle to solve

Hypotenuse would be the flight path

One leg (opposite) is the tree     65 ft

Tan (Θ) = opposite/ adjacent = 65/750  

Θ = arctan (65/750)

Θ = 5°
