Tan(50) = h/40
h = 40 x tan(50)
h = 47.67 or 47.7 feet

Step-by-step explanation:
I hope this helps.
Sorry if I'm wrong.
Rate of change=<span><span>change in y divided by </span><span>change in <span>x
y= 3,6,9
x= 1,2,3
The numbers chosen above are because if mike travels 3 miles in one hours then he can travel 6 miles in two hours and 9 miles in 3 hours.
Change in y = 3
Change in x = 1
3 / 1 = 3
So, the rate of change is 3.</span></span></span>
For perimeter you just add the sides up, so 15+12+9 which = 36
