This article presents a new approximation theorem with elements from some wedge of a continuous condensing mapping in a locally convex Hausdorff space \(E\). This result generalizes some well-known theorems of Fan, Lin, Sehgal and Singh. As applications some fixed point theorems for multivalued \(K\)-set contractive mappings defined on closed balls and annulus values in cones of Banach spaces are given.
