An outdoor staircase has a total vertical elevation of 17.5 feet from the road level to the first floor. The 1st floor to the 2n
d floor is also 17.5 feet. If the angle of elevation is 32.47 degrees and the landing of each step is 11 inches, answer the following questions showing each step of your work:
a) What is the vertical rise per step (in inches, rounded to the nearest inch)?
b) Find the number of steps needed to climb from road level to the 2nd floor.

Using order of operations, we can see we should first solve for the exponents, and then multiply the exponent values by each other.
3²×
9×243
2187
Another way to solve this is to add the exponents together and simply do
. We can only do that in this case, however, because the values are being multiplied by each other.
Either way we solve, we will get 2187 as our final answer.
