OpenStudy (anonymous):
is that that tan(2x) or tan(x) ^2 ?
OpenStudy (anonymous):
tan(2x) sorry
OpenStudy (anonymous):
tan(2x) = sqrt3 2x = tan-1(sqrt3) 2x = pi/3
OpenStudy (anonymous):
x = pi/6
OpenStudy (anonymous):
which is 30 degrees

OpenStudy (anonymous):
so, if x = pi/6, that means that the two angles would be 30 degrees, and 330 degrees, right?
OpenStudy (anonymous):
over (0 to 360 degrees), right?
OpenStudy (anonymous):
Well also, since tan funtion repeats every 180 degrees. Then 30+180=210* is also a valid answer
