Question

I need help finding the answers for this problem

Answer 1

The answer to your question is:

a) 8.2 mi

b) 4.1 mi

c) 4.7 mi

Explanation:

For 30°

sin Ф = opposite leg / hypotenuse

hypotenuse = opposite leg / sin 30

hypotenuse = 4.1 / sin 30 = 4.1 / 0.5

hypotenuse = 8.2 mi

For 90°

d must be 4.1 mi because is over the observer at this angle

For 120°

distance = opposite leg / sin 60

distance = 4.1 / √3/2

= 4.71 mi

I hope it helps you!
