State the point on the line y - 18 = 71.3(x +98)
krek1111 [17]

9514 1404 393

Answer:

  (-98, 18)

Step-by-step explanation:

We recognize the equation as being in the "point-slope" form.

  y -k = m(x -h) . . . . . . . a line with slope m through point (h, k)

__

Comparing this form to the given equation, we identify the parameters as ...

  k = 18, m = 71.3, h = -98

The point on this line is (h, k) = (-98, 18).

An airplane pilot can see the top of a traffic control tower at a 20 degree angle of depression. the airplane is 5,000 feet away
daser333 [38]

The given question describes a right triangle with with one of the angles as 20 degrees and the side adjacent to the angle 20 degrees is of length 5,000 feet. We are looking for the length of the side opposite the angle 20 degrees.

Let the required length be x, then

\tan{20^o}=\cfrac{opp}{hyp}=\cfrac{x}{5,000}\\ \\ \Rightarrow x=5,000\tan{20^o}=1,819.85

Therefore, the height of the airplane above the tower is 1,819.85 feet.
