Question 940085
The angle each ray makes with the x-axis is the same so you can build two triangles. 
The tangent of the common angles is given by the y-coordinate divide by the x-coordinate.
Let the coordinates of A be (x,0).
{{{2/(x-1)=3/(5-x)}}}
{{{2(5-x)=3(x-1)}}}
{{{10-2x=3x-3}}}
{{{-5x=-13}}}
{{{x=13/5}}}
A:({{{13/5}}},{{{0}}})
