DE-BUNDESWETTBEWERB 2019 Problem 7

    Let ABCABC be atriangle with AC‾>BC‾\overline{AC}> \overline{BC} and incircle kk . Let M,W,LM,W,L be the intersections of the median, angle bisector and altitude from point CC respectively. The tangent to kk passing through MM , that is different from ABAB , touch kk in TT . Prove that the angles ∠MTW\angle MTW and ∠TLM\angle TLM are equal.
