    please take over as I have been stuck on this PDE for the last 3 hours and I need to finish tonight
    Nobody helped me

    In an acute-angled triangle ABC the interior bisector of the angle A intersects BC at L and intersects the circumcircle of ABC again at N. From point L perpendiculars are drawn to AB and AC, the feet of these perpendiculars being K and M respectively. Could you please help me prove that the quadrilateral AKNM and the triangle ABC have equal areas?

    Notice that this reduces down to proving that [KLB]+[MLC]=[KLN]+[MLN]. Now notice that the two pairs of triangles share a side, and KL=ML, and so you want to prove that KB+LC=the two perpendicular distances from N to KL and N to ML.
