What is the arc measure of BAC in degrees?
(7n+12)
(13n-16)
(6n)

(6n) Is the arc measure of BAC

Step-by-step explanation:

The arc measure is  the piece not included in the arc, The arc goes counterclockwise starting at the b radius all the way to the c radius. The arc includes (7n+12) and (13n-16) inside of it. (6n) is the chunk left out.

BAC is 276

Step-by-step explanation:

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
