Suppose an airplane is at an altitude of 3500 ft and the angle of elevation from the airport to the plane is 29º. What is the horizontal distance from the plane to the airport? Round to the nearest foot.
|dw:1337099224967:dw| A is the plane P is the airport. Is the diagram clear?
@Lalafuhsho Can you understand the diagram?
From the triangle : Find Tan (Angle D) = tan 29 Also tan D= 3500/x Equate both of them. Find x :)
Yeah I can. Thank you both :)
