Answer:
The answer is the option A
[tex]tan(A)[/tex]
Step-by-step explanation:
we know that
In the right triangle ABC
[tex]tan(A)=\frac{BC}{AB}[/tex]
where
BC is the opposite side to the angle A
AB is the adjacent side to the angle A
we have
[tex]AB=c\ units,BC=a\ units[/tex]
substitute the values
[tex]tan(A)=\frac{a}{c}[/tex]
