Question

find the reference angle 9╥/4 in degrees

Answer 1

Do you know the conversion formula?

Answer 2

yeah im just confused if its the angle toward the x axis or y axis? so it would be 1/4 but which side?

Answer 3

It's over 2pi, so I'll give you a hint, it will be over 180^o

Answer 4

its over 360 I know

Answer 5

so I use the angle connecting the 1/4 radiant and y axis??

Answer 6

no "x-axis" for reference angle
the reference angle or terminal angle is always the smallest angle from the x-axis

\[\frac{9\pi}{4} = \frac{8\pi}{4} +\frac{\pi}{4} = 2\pi + \frac{\pi}{4}\]
