Answer:

We are given that ray CE is an angle bisector of angle ACD. With this, we have the equation,

mACE = mECD

Next, we look at the choices

mECD = mECB > This not possible since ray CD is between the two angles

mACE = mACD > This is still not possible since ray CE is between the two angles

mACE = mDCB > This is possible since angles ACE, ECD and DCB are complementary angles.

mECD = mACD > This is not possible since ray CE is between the two rays

The answer is the third option
