    That's the side. There are 180 degrees in a triangle.

    So to find C, we will add angles A and B then subtract them from 180. \[\angle C=180-(\angle A + \angle B)\]

    \[\angle C =180-(55+44)\]

    Just remember that side B is the smallest, meaning side A should be greater than 68.

    From the choices, find all the choices that are greater than 68 (that's for side A).
