I need help with this one!

Answer:
[tex]\tan A=\frac{10}{24}=\frac{5}{12}[/tex]
Step-by-step explanation:
The easiest way to remember sine, cosine, and tangent ratios is to use SOH-CAH-TOA as an acronym.
SOH - Sine: Opposite over hypotenuse
CAH - Cosine: Adjacent over hypotenuse
TOA - Tangent: Opposite over adjacent
Note that these are referring to the position of the sides relative to the angle you are looking at. In this case, that is angle A. Since it's tangent, we have:
[tex]\tan A=\frac{10}{24}=\frac{5}{12}[/tex]
