The point is $\"\"$ .

\

Consider the point $\"\"$ .

\

Here $\"\"$ is opposite side and $\"\"$ is adjacent side.

\

From the pythagoras theorem,the value of $\"\"$ , here $\"\"$ is hypotenuse.

\

Substitute the values $\"\"$ .

\

Therefore $\"\"$ and $\"\"$ and $\"\"$ .

\

The trigonometric ratios are :

\

(i). $\"\"$ .

\

(ii). $\"\"$

\

(iii). $\"\"$

\

(iv). $\"\"$

\

(v). $\"\"$

\

(vi). $\"\"$

And $\"\"$ , $\"\"$ , $\"\"$ .
