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

If n is equal to 9×7 what should be added to n to make it 233

iris [78.8K]

170 should be added because 9x7 is 63 and you would subtract 63 from 233

The slope between (3, 9) & (6, 12) m=

vivado [14]

Answer: m=1

Step-by-step explanation:

m = (y2 - y1)/(x2 - x1)

Where

y2=12

y1=9

x2=6

x1=3

so plug in your values in the slop formula:

m=(12-9)/(6-3)

=3/3
