An airplane spots the floating debris at an angle of depression of 15 degrees. If the plane is at an altitude of 3000. Feet, wha
hodyreva [135]

Answer:

11196.15 km

Step-by-step explanation:

Consider the attached diagram

If the Airplane is at point A and the floating debris at point C, we want to determine the horizontal distance |AB| before they fly over it.

Using trigonometry

Tan \alpha =\frac{Opposite}{adjacent} \\Tan 15 =\frac{3000}{|AB|}

Cross multiply

|AB|X Tan 15 =3000

|AB| = \frac{3000}{Tan 15} =11196.15 km

Therefore, the horizontal distance |AB| before they fly over it is 11196.15 km

Only pick one
garri49 [273]

Answer:

C

Step-by-step explanation:

Absolute value makes anything in it positive, as distance from 0 can only be positive. So if we apply that to every term, we can find the answer.

For a, simplify and it becomes 15>19. That's false

For b, simplify and it becomes 16<13. Also false

For c, simplify and it becomes 15>12. True

For d, simplify and it becomes 12<8. False

For e, simplify and it becomes 19>20. Very False.

So the only true one is C. So C is the answer.

Hope this helped.
