Explanation
The above image is a representation of a secant theorems. We are given that
[tex]mMF=42\degree and\text{ }mNH=132º,[/tex]
Therefore we can use the formula below;
[tex]\begin{gathered} m\angle C=\frac{1}{2}(mNH-mMF) \\ m\angle C=\frac{1}{2}(132^0-42^0) \\ m\angle C=\frac{1}{2}(90) \\ m\angle C=45^0 \end{gathered}[/tex]
Answer:
[tex]m\angle C=45^0[/tex]
