Check the picture below.
now, the "x" is a constant, the rocket is going up, so "y" is changing and so is the angle, but "x" is always just 15 feet from the observer. That matters because the derivative of a constant is zero.
now, those are the values when the rocket is 30 feet up above.

I hope this helps you

n=m+4
<h3>step-by-step explanation:</h3>
given formula,
n=3m-2l
and,
l=m+2
here in this question We have to substitute the values of "l" in the formulae
we get,
n=3m-2(m+2)
n=3m-2m+4
n=m+4
so if we complete the process correctly we get n=m+4
It’s 4 I hope this helps
Explanation I took this in 9th grade so I know how to do this kind of stuff
