Angle def measures 75. what is the measure of angle cfd?

The measure of ∠CFD is 105°

Step-by-step explanation:

Given the figure of isosceles triangle in which measure of ∠DEF=75°

∠DEF≅∠DFE

we have to find the measure of ∠CFD

As CG is a straight line

Therefore ∠CFD and ∠DFE forms a linear pair

⇒ ∠CFD + ∠DFE=180°

∠CFD + ∠DEF=180°     ( as ∠DEF≅∠DFE)

∠CFD + 75=180°

∠CFD = 180-75=105°

Hence, the measure of ∠CFD is 105°
