An airplane pilot spots the control tower at an angle of depression of 47 degrees. He know that his ground distance is 25,000 feet. What is the distance of the line of sight from the plane to the control tower?

70.30

step-by-step explanation:

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )

      2

  2 is to go somewhat to the top right of a because it is squared    

v= a h/3
