Question

1. Kelly is playing with her drone, which she got from Santa last Christmas. When she flies her

Answer 1

Answer: 686.86 feet

Step-by-step explanation:

Hi, since the situation forms a right triangle (see attachment) we have to apply the next trigonometric function.  

Tan α = opposite side / adjacent side

Where α is the angle of elevation of Kelly's view, the opposite side (x) is the maximum height of the  drone, and the adjacent side is the horizontal distance between Kelly and the drone when it hits the ground.

Replacing with the values given:  

Tan 70 = x/ 250  

Solving for x  

tan70 (250)=x

686.86 ft = x
