A uniform right circular cone of base radius 2a and height 8a rests in equilibrium with its base in contact with the Rough inclined plane the angle of inclination of the plane is then increase steadily. Assuming the plane is sufficiently rough to prevent slipping find the angle of inclination of the plane to the horizontal when the con is about to topple

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
