the angle of incidence will be equal to the angle of emergence when it is in minimum deviation position. Note: At the minimum deviation as the angles of incidence and the angle of emergence are the same, the ray through the prism will be parallel to the base of the prism.
the prism to occur the total internal reflection, the reflecting angle must be more than twice the critical angle of the material. So here the critical angle for flint glass is 36º so the refracting angle must be greater
