A(1,1),B(4,-2),C(5,5) \ \mbox{are the vertices} \\ \\ \mbox{Thus the equations of the sides are} \ x+y=2,x=y,7x-y=30 \\ \\ \mbox{Also it is easy to note now that angle A is} \ 90^{\circ} \\ \\ \mbox{Thus the bisector of A is parallel to x axis} \ \mbox{and its equation is} \ y=1 \\ \\ \mbox{Thus the perpendicular equation is} \ x=k \\ \\ \mbox{But since it has to pass through} \ (5,5) \\ \\ \mbox{Its equation is} \ x=5
