The formula for tangent is,
[tex] tan \theta=\frac{Opposite side}{Adjacent side} [/tex]
In the given triangle ABC, BC is the opposite side and AC is the adjacent side. So,
[tex] tan A=\frac{BC}{AC} [/tex]
[tex] tan A=\frac{7}{24} [/tex]
So, C is the correct choice.
The given triangle is a right triangle which is right angled at angle C.
For angle A the adjacent side is AC,the opposite side is BC while hypotenuse is AB .In the given triangle adjacent =24 ,opposite =7 and hypotenuse =25.
Tan of any angle is the ratio of opposite and adjacent .
Tan =[tex] \frac{opposite}{adjacent} [/tex]
Tan A=[tex] \frac{7}{24} [/tex]
