Magnitude + direction of block on an incline

[jspek9]

A 800 gm block slides down an inclined plane that makes an angle of 30° with the horizontal. It accelerates at 1.5 m/s2. u_k=.4
Find the magnitude and direction of the total force exerted on the block by the plane. For the direction, give the angle as measured counterclockwise from the vertical (in degrees).

Can anyone give me any insight on how to go about this? I'm completely lost.

The Attempt at a Solution

Draw a picture of the block. Draw and label the various forces. If it is being accelerated then there must be a net force that is the cause.

Write an equation and solve.
