Expert Solution
Step 1: Mention the given data.

Depth of slip surface, z equals 6 space straight m

Water level, h equals 1 space straight m

Saturated unit weight, gamma subscript s a t end subscript equals 20 space bevelled kN over straight m cubed

Inclined angle, i equals 10 degree

Cohesionless sand, c apostrophe equals 0

To find: Angle of friction of the soil.
