Question 880517
An airplane is at an altitude of 2400m. the angle of depression to the airport due east is 34 degrees, and the angle of depression to the town due west is 46 degrees. how far apart are the airport from the town.
***
let x=ground distance from town to airplane
let y=ground distance from airplane to airport
..
tan 46˚=2400/x
x=2400/tan 46˚≈2318
..
tan 34˚=2400/y
y=2400/tan 34˚≈3558
..
2318+3558≈5876
how far apart are the airport from the town? 5876m
