Question

Two observers simultaneously see an airplane overhead and between them. They measure

Answer 1

Answer:

2.05 mi

Step-by-step explanation:

I don't see a figure, so I am guessing that the plane is 1.7 miles above the ground.

Let x = distance of observer 1 from that point

     y =  distance of observer 2 from that point

Tan 48 = 1.7/x           and    tan 73 = 1.7/y

x tan 48 = 1.7                       y tan 73 = 1.7

x = 1.7/tan 48                         y = 1.7/tan 73

x + y = distance between the observers

x + y = 1.7/tan 48 + 1.7/tan 73

       = 2.05 mi
