Step-by-step explanation:
The answer is A I’m pretty sure
Choice b would be correct since the slope of the line is negative !
Given :
Angle of elevation, Ф = 24°.
Distance of Sam from launchpad, D = 5 miles.
To Find :
How high is the rocket.
Solution :
Let, height is h.
We know, tan Ф is given by :

Hence, this is the required solution.
Let's assume the laptop is opened at 90 degrees (this is done for the sake of simplicity, is actually irrelevant) then each plane would be analogous to the 'x' and 'y' planes you see in a Cartesian Plane, which only intersect at one point called the Origin. Any two lines with different slopes will intersect only one time (if they're parallel they have the same slope)
