Refer to the diagram shown below.
The height is h ft
Half of the total horizontal base length is w ft.
Because the pitch is 8, therefore
When w = 12 ft, then h = 8 ft.
That is
w/h = 12/8
w = 1.5h
The slope is h/w = 8/12 = 2/3.
As an angle,
θ = tan⁻¹ 2/3 = 33.7°
Answer:
Slope = 2/3.
The slope represents an angle of elevation of 33.7°.
