Determine the slope angle for an infinite slope that is made using a soil with no cohesion and having internal friction angle of 30° and saturated unit weight of 20 kN/m². The factor of safety for the slope is taken to be 1.5 and the unit weight of water as 10 kN/m².

Refer to Figure 15.50. Given that β = 55°, γ = 19 kN/m3, ϕ′ = 17°, c′ = 57.4 kN/m2, and H = 13.7 m, determine the factor of safety with respect to sliding. Assume that the critical sliding surface is a plane.
