it also says Solve the following trigonometric equation for the interval
(0,2].

anybody out there to help me
OpenStudy (btaylor):
If you simplify, you get sin(x) = 3/23.
So, there is some triangle that looks like this:|dw:1385584588832:dw|
Using the inverse sine (arcsine), we find that x = 0.131 rad = 7.5 degrees.
This could also occur in the 2nd quadrant, so 180-7.5 = 172.5 degrees
or 1.44 radians.
