Median and Altitude of a Triangle

In the diagram, TK is a median. Find KS if RS=14

In the diagram, QS and RT are medians. If $$PT=3x-1$$ , $$PS=4x-2$$ , and $$SR=2x+4$$ . Find TQ

Find DC if $$DC=x+5$$ and $$HC=x-3$$

In the isosceles triangle, PN is an altitude and $$m\angle M=40\degree$$ , find $$m\angle MPN$$

AC is an altitude of the triangle. Find $$m\angle1$$ . The $$m\angle CAD=50\degree$$

Find x. AD is an altitude of triangle ABC

MK is an angle bisector. If $$m\angle2=50\degree$$ , what is $$m\angle1$$ ?

MK is an angle bisector, $$m\angle1=2n+10,\ m\angle2=4n-32,\ and\ m\angle L=60\degree$$ find $$m\angle G$$
