This is for 20 points!!!!!!!

All really need to do is pick one number. so, we will go with 6 and 87.

6 times 12 is 72 then you subtract that from $87.

That would be 15

To double check, you can use another one. 9 and 123.

9 times 12 is 108. subtract that from 123 and you get 15.

Your answer is B) $15

Hope I helped :)

Circle D is below what is the arc measure of BC in degrees
maks197457 [2]

Answer:

84°

Step-by-step explanation:

\because (13n - 16) \degree + (7n  + 12) \degree + (6n)\degree \\= 360\degree \\  \\  \therefore \: (26n - 4) \degree= 360\degree \\  \\  \therefore \: 26n - 4= 360 \\  \\ \therefore \: 26n = 360 + 4 \\  \\ \therefore \: 26n = 364 \\  \\ \therefore \: n =  \frac{364}{26}  \\  \\ \therefore \: n =  14 \\  \\\because  m\overset { \frown}{BC} = (6n)°\\  \\\therefore \:m \overset { \frown}{BC} =(6\times 14)°  \\  \\   \huge \purple {\boxed {\therefore \:m\overset { \frown}{BC}= 84°}} \\
