i think it is a typo, because the answer is none of these
OpenStudy (bohotness):
wertid i just put it in and none are here
OpenStudy (bohotness):
-_-
OpenStudy (bohotness):
sin2x/cos 2x = 1
tan2x = 1
2x = 45
x = 22.5 <--- you should have this as a answer
OpenStudy (freckles):
use double angle identity
sin(2x)=2sin(x)cos(x)

There should be a common factor on top and bottom
OpenStudy (freckles):
@wolverine75 can you tell me a factor you can "cancel"
OpenStudy (lizz123):
tan2x = 1
2x = 45
x = 22.5
@wolverine75
OpenStudy (bohotness):
I JUST SAID THAT
OpenStudy (anonymous):
well sin2x is the same as 2sinxcosx

@freckles
OpenStudy (freckles):
sin(x)/cos(x) = tan(x) doesn't it?

OpenStudy (freckles):
so what is 2 * sin(x)/cos(x) equal to?
OpenStudy (anonymous):
2tanx ?
OpenStudy (freckles):
awesomeness

THANK YOU SO MUCH!!!!
