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

Answer:
5%
Step-by-step explanation:
Probability is the likelihood of an event taking place.
-Given there are 95 white and 5 blue pieces, the total number of papers is 100.
-The theoretical first attempt probability is equivalent to the number of each paper divided by the total:
Hence, the theoretical probability that a blind-folded person draws a blue piece of paper on the first attempt is 0.05 or 5%
