(50pts + correct and best gets brainliest) in the diagram below, de and ef are tangent to o. which equation could be solved to find x, the measure of df? a. 1/2(228 + 48) = x b. 1/2(228 - 48) = x c. 1/2(228 + x) = 48 d. 1/2(228 - x) = 48

D. 1/2(228 - x) = 48

Step-by-step explanation:

<e = 1/2(dgf-df)

48 = 1/2(228-x)

x = 132.

Step-by-step explanation:

Given information: DE and EF are tangent to O.

According to the two tangent theorem, if two tangent intersect each other then the angle form by them is half of the difference of major arc and minor arc.

Using the two tangent theorem, we get

Multiply both sides by 2.

Multiply both sides by -1.

Therefore, the value of x is 132.

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
