Vladimir79 [104]

Answer:

$d=8610.1ft$

Step-by-step explanation:

From the question we are told that:

Angle $\theta =6\textdegree$

Height of plane $h=900ft$

Generally the trigonometric equation for distance flown d is mathematically given by

$sin \theta=\frac{h}{d}$

Therefore

$d=\frac{h}{sin\theta}$

$d=\frac{900}{sin6}$

$d=8610.1ft$
