    Please see the attached file for detailed solution.

    A block rest on an inclined plane. Its angle with the horizontal is increased. When the angle becomes 40°, the block starts to slide. Calculate the coefficient of static friction us between the block and the plane.

    In the above graph where you labeled 50°, it should be 40°, which is the angle between the weight and the normal force.

    In the direction perpendicular to the incline, the normal force
    In the direction parallel to the incline, the static friction
    Therefore, the coefficient of static friction is
