Find the measure of the reference angle for a

∘
170^\circ
17
0
∘
angle.
Identify Quadrant:
170
°
170°
170°
is more than
90
°
90°
90°
but less than
180
°
180°
180°
, so it's in the
2
2
2
nd quadrant.
Subtract from
180
°
180°
180°
:
For angles in the
2
2
2
nd quadrant, subtract the angle from
180
°
180°
180°
to get the reference angle.
Calculate Reference Angle:
So, the reference angle is
180
°
−
170
°
180° - 170°
180°
−
170°
.
Calculate Reference Angle:
So, the reference angle is
180
°
−
170
°
180° - 170°
180°
−
170°
.Calculating that gives us
180
°
−
170
°
=
10
°
180° - 170° = 10°
180°
−
170°
=
10°
