Wrong bro answer was the small triangles length square divided by big angle square into x


I wrote (4/9)^2 = (y^2) / (x^2 + y^2 )
Is it correct ?
May be i solve it in a wrong way

It was (6,-2) I think, because the shape moved 6 steps to the right on the xaxis and 2 steps down on the yaxis. I forgot the exact number of steps it moved.
