Question

cdef ≅ turs. what is m∠c?

Explanation:

Step1: Recall property of congruent polygons

Corresponding angles of congruent polygons are equal. Since $CDEF\cong TURS$, $\angle C$ corresponds to $\angle T$.

Step2: Identify measure of corresponding angle

We see that $m\angle T = 66^{\circ}$. So $m\angle C=m\angle T$.

Answer:

$66$
