Moment due to beam weight is W*L^2/2. W is weight per unit length, L is length of the cantilever. Total beam weight is WL. Moment arm is L/2 since the weight of the beam acts at the middle point of the beam. Therefore M=W*L^2/2.

Alf's diagram is my understanding of the statement of the problem as well. The moment due to the inclined load can be calculated using the distance measured from the end of the beam perpendicular to a line acting through the load, as shown in the diagram. OR you can use trigonometry to break the inclined load into horizontal and vertical components. Then the moment is equal to the vertical component times the length of the cantilever. The horizontal component has no affect on the bending moment.
