| **In the triangle DEF from the vertex D, the median DM and the bisector of the inner angle DL are drawn, with DM = 1 / 2EF and the angle DLF = 65 deg. Find the corners of the triangle DEF.**

We will consider the median DM, it is half of the EF, so DM = EM.

DMF and DME are isosceles, further it should be said that med angle = mde angle.

Angle D = F + E.

The sum of the angles, as we know, is 180.

angle F = 180 – 65 – 45 = 70 °, E = 180 – 90 – 70 = 20 °.

Our answer is 20 °.
