Answer:
2728.11m
Step-by-step explanation:
The height of the plane is 1020m
The airport makes an angle of elevation of 20.50° with the plane
The distance of the plane from the airport = ?
See attached document for better illustration of the position of the plane and airport
Using SOHCAHTOA,
tanΘ = opposite/ adjacent
θ = 20.50°
opposite = 1020m
adjacent = ? = x
Tanθ = opposite/ adjacent
Tan20.50 = 1020 / x
X = 1020 / tan20.50
X = 1020 / 0.37388
X = 2728.11m
The distance of the plane from the airport is 2728.11m
