In the diagram below, DE and EF are tangent to O. Which equation could be solved to find X, the measure of DF.
Brut [27]

Answer:

The answer to your question is letter D

Step-by-step explanation:

Formula

                     m∠E = \frac{1}{2} ( DGF - DF)

Data

m∠E = 48°

DGF = 228°

DF = x°

Substitution

                    48° = \frac{1}{2} ( 228° - x°)

Solution

                                     2(48) = 228 - x°

                                     96 = 228 - x°

                                     96 - 228 = - x°

                                    - 132 = - x°

                                       x° = 132°
