Answer:

Step-by-step explanation:

C and 110° are opposite angles of a cyclic quadrilateral.

Opposite angles of a cyclic quadrilateral are supplementary.

$\therefore \: c \degree + 110 \degree = 180 \degree \\ \therefore \: c \degree = 180 \degree - 110 \degree \\ \therefore \: c \degree = 70 \degree \\ \therefore \: c = 70$
