Is there a slope or is it undefined?

12/72 = 1/6

the slope can be found by using the equation





tangent A = length of opposite side / length of adjacent side





where A is the angle that tells you the slope



opposite side is the height 12



adjacent side is the width 72





so





tangent A = 12/72





that is assuming that the roof is high on one end and not peaking in the middle, in which case, you would use 36 as the opposite side

rise over run isn't pre-calc, it's pre-algebra.





12/72 = 1/6

sqrt(72^2-12^2)= 70.99 ft





s=12/71 = .169
