As AB is a diameter, then m∠CBA=180^{0}-75^{0}=105^{0}.
∠CBA is a central angle, so its measure multiplied by radius is the length of arc AC.
Note that
![105^{0}=7\cdot 15^0](https://tex.z-dn.net/?f=105%5E%7B0%7D%3D7%5Ccdot%2015%5E0)
and
![15^{0}= \frac{\pi}{12}](https://tex.z-dn.net/?f=15%5E%7B0%7D%3D%20%5Cfrac%7B%5Cpi%7D%7B12%7D%20)
. Then
![105^{0}= \frac{7\pi}{12} = \frac{7\cdot 3.14}{12}=1.83](https://tex.z-dn.net/?f=105%5E%7B0%7D%3D%20%5Cfrac%7B7%5Cpi%7D%7B12%7D%20%3D%20%5Cfrac%7B7%5Ccdot%203.14%7D%7B12%7D%3D1.83%20)
and length of the arc is
![12\cdot 1.83=21,96](https://tex.z-dn.net/?f=12%5Ccdot%201.83%3D21%2C96)
.The correct answer is 22 in.

Answer:
1/4 for both
Step-by-step explanation:
2/8 -- you divide 2 by 2 you get 1, 8 divided by 2 is 4 -- 1/4
3/12 -- you divide 3 by 3 you get 1, 12 divided by 3 is 4 -- 1/4
** tip: what you do to one half of the fraction you have to do to the other
hope this helps!
