Answer:
[tex]\frac{1}{2}[/tex]
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
In the right triangle ABC of the figure, the tangent of angle C is equal to divide the opposite side to angle C (side AB) by the adjacent side to angle C (side BC)
so
[tex]tan(C)=\frac{AB}{BC}[/tex]
substitute the given values
[tex]tan(C)=\frac{11}{22}[/tex]
simplify
[tex]tan(C)=\frac{1}{2}[/tex]
