Step-by-step explanation: We are to find the value of c from the figure shown.
We see from the figure that
a quadrilateral is inscribed in a circle with opposite pairs of angles with measurements (c° and 96°) and (d° and 100°). So, the given quadrilateral is a cyclic one.
We know that
the sum of the measurements of the opposite angles of a cyclic quadrilateral is 180°.
