Step-by-step explanation:
<u>Inequalities with Absolute Value</u>
We must recall the following rule:

Then:

We have the following inequality:

Subtracting 12:


Applying the rule:

Adding 4:

Operating:

Dividing by 13:

The solution expressed in interval form is:

A is the intercepted arc of the angle that measures 45 degrees. The rule here is that arc measures twice what the angle measures. If the angle measures 45 degrees, then the arc measures 45 * 2 which is 90 degrees. There has to be another choice there that is cut off. These are inscribed angles, and those are the rules for inscribed angles.
Answer:
>20 degrees
Step-by-step explanation:
Answer:
C:7
Step-by-step explanation:
Complementary is what else to add to equal 90 degrees. 10 is complementary to 80 because 80+10=90. Supplementary is what would equal to 180. Complementary is usually used in an right angle and supplementary in a line.
