Answer:
Step-by-step explanation:
From the given figure it is clear that we two rays because both sides have one endpoint and goes on infinitely in only one direction.
If a ray has end point at A and goes on infinitely in only one direction towards point B, then ray is denoted as .
For first side, we have point V as end point and ray goes goes on infinitely in only one direction towards point U. So, first side is .
For second side, we have point V as end point and ray goes goes on infinitely in only one direction towards point W. So, second side is .
Therefore, the sides are .
Given:
In circle O, m∠R = 30.8°.
To find:
The m∠NOQ
Solution:
Central angle theorem: According to this theorem, the central angle is always twice of subtended angle on the same arc.
Angle NOQ and angle NRQ are on the same arc but ∠NOQ is the central angle and ∠NRQ is the subtended angle on the arc NQ.
Using central angle theorem, we get
Therefore, .
