Answer: 6 and -6
Step-by-step explanation:
6 Is the distance from zero, since distance cannot be negative, it does not matter if we go left or right on the number line, it will still be 6 units away from zero.
Answer: 68

Explanation:
Segment EC is a diameter as it goes through the circle center point O. So arc EDC is 180 degrees in measure.
Arc EDC is composed of the minor arcs DE and DC.
In other words, the two minor arcs mentioned add up to 180 degrees
We want to know DE and we know that DC = 112
So,
(minor arc DE) + (minor arc DC) = arc EDC
(minor arc DE) + (minor arc DC) = 180
(minor arc DE) + (112) = 180
(minor arc DE) + 112 - 112 = 180 - 112
minor arc DE = 68
Ok, so you already know that mQBO = 3x-15°
You just need to find x.
You use mSAO and mQAO to solve for x. You can also see that triangle AOS and triangle AQO are similar. Solve these two equations for x and mAOQ:
90+(2x+6)+mAOQ = 180
90+(4x-12)+mAOS = 180
x=9 and mAOQ=mAOS=66°
Now you can find mQBO, by simple algebra:
3x-15=3*9-15=12
So, mQBO is12 degrees.
All of the examples provided are all parallel to each other
