Question

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

Answer 1

1/2 (228-x)=48

Explanation:

Just got the question correct.

Answer 2

The answer to your question is letter D

Explanation:

Formula

m∠E =
`(1)/(2) ( DGF - DF)`

Data

m∠E = 48°

DGF = 228°

DF = x°

Substitution

48° =
`(1)/(2) ( 228° - x°)`

Solution

2(48) = 228 - x°

96 = 228 - x°

96 - 228 = - x°

- 132 = - x°

x° = 132°
