It is 0 because of the sin being 0
right triangle
c^2 = a^2+b^2
30^2 = 24^2+18^2
900 = 576 +324
900 = 900

In case you're not already aware, the expression 
is called the "difference quotient" and represents the average rate of change of a function 
over an interval ![[x,x+h]](https://tex.z-dn.net/?f=%5Bx%2Cx%2Bh%5D)
.
For the function 
, by substituting 
we get
Then the difference quotient is
where the last equality holds as long as 
.
176 divided by 8 = 22
So 176 can be evenly divided by 8
