<u>Examining the question:</u>
We are given the expression:
We know from Basic trigonometry that:
<u>Simplifying the expression:</u>
Replacing these values in the given expression, we get:
Since the denominator of both the values in the denominator is the same:
We know that 
= 
, using the same property:
and we are done!

I think the question for this problem is to find the slope of the staircase. The slope is a ratio of change of the y-coordinates and x-coordinates of points. It is written as Δy/Δx especially in analytical geometry. It could also be simply the ratio of the rise or vertical height to the run or horizontal length.
Therefore, the slope of the stair case is
Slope = rise/run = 14/20 = 0.7
