Answer:
Step-by-step explanation:
Please refer to the attached figure for the labeling and construction in the given figure:
Given that minor angle of arc AB is .
Or in other words, we can say that angle subtended on the center O by the arc is .
Now, PA and PB are the tangents so, if we join the center of circle O with A and B, the angles formed are right angles.
i.e.
Now, we know that sum of internal angles of a quadrilateral is equal to .
Here, we have the quadrilateral AOPB.
Hence, the correct answer is:
8-(-4)
-4-0
12/-4=-3
1/3 is the slope perpendicular to line m

Answer:
B. Minor arc
Step-by-step explanation:
The central angle that is subtended by arc XY is less than 180° and it is not up to a semicircle.
A semicircle is half of a circle of which its central angle measure exactly 180°
The central angle of which an arc is subtended measures more than 180°.
Therefore, arc XY, which has a central angle that subtends it measuring 155° can be said to be a minor arc.
Answer:
8
Step-by-step explanation:
Vertical angles are congruent, so 9n=8n+8. It follows that n=8.
