Hope everything is clear; if you need any clarification/explanation, kindly let me know, and I'll comment and/or edit my answer :)
Answer:
tanΘ = 
Step-by-step explanation:
tanΘ = 
the opposite side requires to be found.
let the opposite side be x then using Pythagoras' identity in the right triangle
x² + 12² = 20²
x² + 144 = 400 ( subtract 144 from both sides )
x² = 256 ( take square root of both sides )
x = 
= 16
then
tanΘ = 
=
C does.
We only want to add whole positive numbers.
C does this by taking the absolute values of the numbers (-8) turns in to +8.
The other choices would take away from the overall total of floors traveled.
