7. Find the given trigonometric ratio

A right-angled triangle formed with the $x$-axis has one of its vertices at $(x , y)$ $=$ $(16,15)$. If one of the legs of the triangle from the origin subtends an angle $\theta$ with the $x$-axis, then find the ratio of $\tan \theta$.

 

Answer:

 

$\tan \theta$ $=$ $\frac{i}{i}$
