Answer:
If you are asking S/4=4 (as in what does S equal) the answer is 16
Step-by-step explanation:
4x4= 16
so 16/4=4 :)
Part A
The angle of elevation of the staire case is given by

Part B:
<span>If
the landing of each step is changed to 17 inches and the elevation of
each step to 21 inches, the new angle of elevation for the
staircase is given by

We'll use the Pythagorean Theorem
130^2 = side^2 +50^2
side ^ 2 = 16,900 -2,500
side ^ 2 = 14,400
side = square root (14,400)
side = 120 feet
