Please help me understand the question

The major arc DGF and the minor arc FD both make up the circle, so their measures should add to 360°.

(arc DGF) + 153° = 360°

arc DGF = 207°

9514 1404 393

  C.  207°

Step-by-step explanation:

Points D and F divide the circle into two arcs. The short arc is referred to by its end point: arc DF. The long arc has the same end points, so is referred to using a third point somewhere on the arc. That point is G.

Together, arcs DF and DGF make the complete circle, or 360°. The measure of long arc DGF can be found from that fact:

  DF +DGF = 360°

  153° +DGF = 360° . . . . substitute the given value for arc DF

  DGF = 360° - 153°

  arc DGF = 207°

Additional comment

The tangents and external angle are completely irrelevant to the question asked by this problem.

3=log(n)=2

answer a: product property

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)
