In the diagram below, de and ef are tangent to o what is the measure of dgf



Step-by-step explanation:

D. 86

Step-by-step explanation:

i got it right

C. 63°

Step-by-step explanation:

<E =  1/2 (243 - 117)

<E = 1/2 (126)

< E = 63

C) 1/2(y-127) = 53

Step-by-step explanation:

When an angle is formed by two secants, a secant and a tangent, or two tangents, the measure of the angle is equal to one-half of the difference between the intercepted arcs.

In this circle, our intercepted arcs are y° and 127°.  Their difference would be (y-127).  One-half of this would be 1/2(y-127).  The angle measure is 53; this gives us

1/2(y-127) = 53

brainliest please please please


Step-by-step expanation:


Step-by-step explanation:

we know that

The inscribed angle measures half that of the arc comprising

in this problem

m∠DGF -----> is a inscribed angle

m∠DGF=\frac{1}{2}(arc\ DF)

we have

arc\ DF=153\°



we know that

arc\ DGF+arc\ DF=360\°

Find the measure of arc DGF

arc\ DGF=360\°-arc\ DF

arc\ DGF=360\°-153\°=207\°


the answer is

a) the measure of inscribed angle m∠DGF is 76.5\°

b) the measure of arc DGF is 207\°

I hope this helps you
