Slope = Rise/Run
Slope = 7.5/12.27 = 0.61

Tg s = 7.5/12.27 =0.611
the angle is 31°4

could it be like finding the hypothenuse
s^2 = (7.5)^2 + (12.27)^2
s^2 = 56.25 + 150.5529
s^2 = 206.8029
s = sqrt206.8029
s = 14.38 ft ==> my answer

Let
7.5 = height
12.27 = base
- - - - - - - - -
Divide 7.5 by 12.27 to get the decimal
7.5 / 12/27 = 0.611246944
- - - - - - - - -
arctan function
0.611246944 = 31.43523173°
31.4° rounded to one decimal place
- - - - - - - - -s-

slope=rise/run
rise=7.5ft
run=12.27ft
slope=7.5/12.27
