The statement makes sense.

Work Step by Step

Let us consider the statement, “I am given that $\tan \theta =\frac{3}{5}$ , so I can conclude that $y=3$ and $x=5$.” According to the trigonometric functions, the value of the tangent function is given by $\tan \theta =\frac{y}{x}$ Put $5$ for $x$ and $3$ for $y$. $\tan \theta =\frac{3}{5}$ Thus, the statement makes sense.
