Find the reference angle for a given angle of $345^circ$ in the unit circle.
Answer 1
Abigail Nelson
To find the reference angle for $345^\circ$, note that it is in the fourth quadrant. The reference angle in the fourth quadrant is found by subtracting the given angle from $360^\circ$:
$ 360^\circ – 345^\circ = 15^\circ $
So, the reference angle for $345^\circ$ is:
$ 15^\circ $
Answer 2
Benjamin Clark
In the unit circle, to find the reference angle for $345^circ$, we subtract it from $360^circ$ because it is located in the fourth quadrant:
$ 360^circ – 345^circ = 15^circ $
Thus, the reference angle is:
$ 15^circ $
Answer 3
Henry Green
For $345^circ$, reference angle:
$ 360^circ – 345^circ = 15^circ $
So, reference angle:
$ 15^circ $
