Hi husker11, welcome to PF.

Show your free body diagram, please, we can not help without seeing it. You can draw in Paint, and save it in jpg format. You can upload the picture if you click on "Go Advanced" and then "Manage Attachments".

Your freebody diagram should show a force vector due to gravity.

Use what you know about triangles to work out what other angles on the diagram are also 35 degrees, 90 degrees or 90-35 degrees.

Then use basic trig functions (eg Cos, Sin, Tan) to calculate the components acting normal to the plane and/or down the plane.
