To find the angle measure, we use a trigonometric formula
For the angle C, we need to relate the angle c and a
c is the opposite hick and a is the adjacent hick.
To relate them, we use
tan(C) = opposite hick / adjacent hick
[tex]\begin{gathered} \tan (C)=\frac{c}{a} \\ C=\tan ^{-1}(\frac{c}{a}) \end{gathered}[/tex]
