![.A granular soil has a saturated unit weight of 20 kN/m³ and an effective angle of shearing
resistance of 30°. The unit weight of water is 9.81 kN/m³. A slope is to be made on this soil
deposit in which the seepage occurs parallel to the slope up to the free surface. Under this
seepage condition for a factor of safety of 1.5, the safe slope angle (in degree, round off to 1
decimal place) would be](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F859da0fd-02fb-4698-ab8f-ee0f7a59c9b8%2F06ed7703-d830-48ba-bd2a-4707be882e49%2F8oq94lh_processed.jpeg&w=3840&q=75)
