How do you find reference angles. Ex. 1. Find the reference angle for -71° 2. Find the reference angle for 697° 3. Find the reference angle for -987° 4. Find the reference angle for -467° 5. Find the reference angle for 323°
OpenStudy (anonymous):
its 180 - that angle do consider signs
OpenStudy (anonymous):
180-(-71)= 180+71=251
OpenStudy (anonymous):
Does that go for all angles, because if you do that for example 3 you get 1167°
OpenStudy (anonymous):
yep

I'm pretty sure that rule only applies to angles that are in the second quadrant.
