Question

The reference angle for 305 degrees is_____.

Answer 1

Since the angle 305 is in the fourth quadrant. The reference angle formula is
Ar=360 degree- Ac
Ar=360 degree-305 degree. The reference angle is Ar=55 degree

Answer 2

reference angle of 305 degrees is 55°

Explanation:

The given angle is 305 degrees.

Thus,
`\theta=305^(\circ)`

The angle is in fourth quadrant. Hence, the reference is given by

`360-\theta`

Substituting the known value, the reference angle is

`360-305\\\\=55^(\circ)`

Hence, reference angle of 305 degrees is 55°
