Here the angle is negative, so for reference angle just find its absolute value:

What is:

|-48| = ??

anonymous · Answer

My Internet is very slow..

anonymous · Answer

So:

-(-48) = 48

Therefore its reference angle is $48^{\circ}$..

anonymous · Answer

Did you understand it or not?? @Lulu212

anonymous · Answer

sort of when i was taught how to do the others it said to find the smallest multiple of 90 that is more than the angle you are finding and subtract from what you have

anonymous · Answer

Yeah that is the case when theta is in 3rd quadrant..

Here, theta is in 4th Quadrant...

anonymous · Answer

Ex. find the reference angle of 210 (90x3=270) 2

anonymous · Answer

270-210=60

anonymous · Answer

That is what I am saying if theta is in 3rd Quadrant then you will subtract it from 270 always..

anonymous · Answer

but in this case it is in the ? Quadrant

anonymous · Answer

Here in your example theta is in 3rd quadrant..
