Question

find the reference angle for the given angle:
780 degrees

Answer 1

please help o-o'

Answer 2

780 = 360 + 360 + 60
Reference angle = 60 :P

Answer 3

so if the angle is bigger than 360 i subtract? o.o

Answer 4

For example?

Answer 5

810 degrees-360=450-360=90 so would 90 be the reference angle?

Answer 6

Oh... 810 = 360 + 360+ 90
Reference angle= 90

Answer 7

ooooh okie dokie i get this. but i had a question about negative angles too like: -199 degrees i'm confused on how to solve for it

Answer 8

-199 = 360-199 = 161 = 180 - 161 = 19 <- reference angle

Answer 9

-x = negative a angle is equal to 360 + (-x) = 360 -x

Answer 10

still a little confused ^^'

Answer 11

Which part?

Answer 12

the last part

Answer 13

Far to my knowledge, reference angle is angle less than /equal to 90

Answer 14

ooh ok thx ^_^

Answer 15

and angle in quad II (that is 90<x<180)
reference angle = 180-x
angle in quad III (that is 180<x<270)
reference angle = 180+x
angle in quad IV (that is 270<x<360)
reference angle = 360 - x

Answer 16

ok thx i got it
