Answer: a.opp/adj
Step-by-step explanation:
The tangent function, along with sine and cosine, is one of the three most common trigonometric functions.
For any given angle x
[tex]\tan\ x=\frac{\sin\ x}{\cos\ x}=\frac{\frac{\text{side opposite to x}}{\text{hypotenuse}}}{\frac{\text{side adjacent to x}}{\text{hypotenuse}}}\\\Rightarrow\tan\ x=\frac{\text{side opposite to x}}{\text{side adjacent to x}}[/tex]
thus, opp/adj correctly describes the tangent function.
