You can think of the protein the same way as the lipid bilayer. It projects its non-polar parts to the non-polar solution, and its polar parts to the polar solution. So in the lipid environment, its non-polars are pointing out toward solution and polar inward away from solution and vice versa for an aqueous environment.
You are correct...Secondary is the answer
