Angles on a straight line add up to 180° so all you have to do is:

180 - 75 = 105

So CFD = 105°

Answer:

The Value of Angle CFD is 105°

Step-by-step explanation:

As you mentioned in the question, Triangle DEF is an isosceles triangle so angles DEF and DFE have the same degree value. If Angle DEF measures 75° then Angle DFE measures 75° as well.

A straight line has an Angle of 180°. Seeing as how CFE is a straight line and Angle DFE is 75°. We can subtract 75° from 180° in order to get the Angle CFD.

[tex]180-75 = 105[/tex]

So the Value of Angle CFD is 105°
