A light ray in the core $(n1=1\mathrm{.}57)$ of a cylindrical optical fiber travels at an angle ${}_1=66$ with respect to the axis of the fiber. A ray is transmitted through the cladding $(n2=1\mathrm{.}2)$ and into the air. What angle ${}_2$ does the exiting ray make with the outside surface of the cladding? Express your answer in degrees.
