Step-by-step explanation:
≈
The diameter of the the circle would be 15.92 mm so if you rounded that up it would 16.
Answer:
Step-by-step explanation: its c. x+ 5
Answer:
A nice way to show it is through the unit circle.
In the unit circle, the point at angle theta from the origin has a y value of sin theta.
If you rotate a point 360-theta degrees from the origin, that is like rotating it theta degrees "backwards", or downwards, which is going to yield the same exact point, reflected through the x-axis. In other words, the y value, or sin(360-theta), is exactly -sin(theta).
