You are mapping metamorphic rocks and you notice a lineation within the rocks. At five different outcrops you measure the pitch of the lineation on an exposed planar rock surface (not necessarily the same structural surface at each outcrop). The table below lists the attitude of each exposed surface and the pitch of the lineation on that surface.

You hypothesize that this lineation represents a planar fabric within the rock. Test this idea by determining whether these five lineation orientations are coplanar. If so, what is the attitude of the plane?
