Answer:
1738.67 feet
Step-by-step explanation:
Imagine a right angles triangle, with the base length of 1800ft and the angle between the base and the hypotenuse to be 15 degrees.
Now, we have to calculate the hypotenuse length, using trigonometric ratios
The ratio that links adjacent side and hypotenuse is cos
So, write an equation:
cos(15) = Adjacent/Hypotenuse = 1800/H
Rearrange to solve.
H = cos(15) x 1800 = 1738.67
This is the distance flown by the aeroplane .
