line ef is tangent to circle g at point a. if the measure of < cae is 95°, what is the measure of arc cba? °

Step-by-step explanation:

You must exclude any intersecting faces (faces that are shared), because these faces are not on the surface.

For example, an ice cream cone can be approximated as a composite figure of a hemisphere on top of a cone.  The circular base of the hemisphere and the circular base of the cone are intersecting, so you must exclude it when finding the surface area.
