I will given you a string of inequalities; you will need to supply the logic!
DM=CM=BM=DE (look for isosceles triangles)
Compare an equilateral triangle with side DM with triangle DCM...DC<DM
I think you can now show that all the other segments are bigger than DC.
THERE ARE SERIOUS PROBLEMS WITH YOUR FIGURE AS SUBMITTED; THIS INVALIDATES MY PREVIOUS ANSWER!!!!!
Look at the angles at point D; they are supplementary in the drawing...but 96+61≠180.
Look at the angles at point M: angle CMB is indicated as a right angle, which means angle CME is also a right angle, but 58+42≠90.
I suggest that you check on the drawing and make sure you submitted it correctly. If there is no transcription error, then the problem is incorrectly drawn.
