Question

A disabled jet can glide at an angle of 11 degrees with the horizontal. If it starts to glide an altitude of 12,000 ft, can it reach a landing strip that is 10miles away?

Answer 1

Answer:

No, the jet can not reach a landing strip that is 10 miles away.

Step-by-step explanation:

It is given that a disabled jet can glide at an angle of 11 degrees with the horizontal. It starts to glide an altitude of 12,000 ft.

We know that,

1 ft = 0.000189394 miles

12000 ft = 2.2727273 miles

In a right angled triangle

$\tan \theta=\frac{perpendicular}{base}$

$\tan (11^{\circ})=\frac{2.2727273}{base}$

$base=\frac{2.2727273}{\tan (11^{\circ})}$

$base=\frac{2.2727273}{0.194380309138}$

$base=11.6921683584$

$base\approx 11.69$

Since 11.69>10, therefore jet can not reach a landing strip that is 10 miles away. The required answer is no.
