Your credit card has a balance of $5400 and an annual interest rate of 17%. You decide to pay off the balance over two years. If
there are no further purchases charged to the card, you must pay $266.94 each month, and you will pay a total interest of $1006.56. Assume you decide to pay off the balance over one year rather than two. How much more must you pay each month and how much less will you pay in total interest?

Option C:
The measure of arc CD is 40°.
Solution:
Given data:
m∠X = 11° and m(arc AB) = 18°
To find the measure of arc CD:
We know that,
<em>Angle formed by two intersecting secants outside the circle is equal to half of the difference between the intercepted arcs.</em>
Multiply by 2 on both sides.
22° = arc CD - 18°
Add 18° from both sides.
40° = arc CD
Switch the sides.
arc CD = 40°
Hence the measure of arc CD is 40°.
Option B is the correct answer.
