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

Step-by-step explanation:
1.
Rises 6 inches for every horizontal change of 16 inches
Slope = rise/run
Slope = 6/16
Slope = 3/8
2.
Rises 3 feet for every horizontal change of 12 feet
Slope = rise/run
Slope = 3/12
Slope = 1/4
