Question

Triangle DEF is an isosceles, so DEF = DFE.

Answer 1

Answer:

m∠CFD=$105\°$

Step-by-step explanation:

we know that

m∠CFD+m∠DFE=$180\°$ ------> by supplementary angles

we have

that

m∠DFE=m∠DEF=$75\°$

so

m∠CFD+$75\°=180\°$

m∠CFD=$180\°-75\°=105\°$

Answer 2

I believe its 105 degrees
