An illustration showing three large wooden barrels arranged horizontally, touching each other. A slanted wooden ramp is placed on top of the first barrel, extending downwards towards the ground. The ramp appears tangent to the first barrel, and the ground also appears tangent to the first barrel. An arc measure of 165° is shown, likely representing the major arc intercepted by the angle formed by the ramp and the ground. The angle between the slanted surface and the ground is marked with a question mark.
