Therefore since the trig equation we are solving is sin and it ... and the other between \(270^\circ\) and \(360^\circ\). \(\sin x^\circ = - 0.349\) Since this is sin, but negative this means ...

The period is 360° so to find the next solutions subtract 360°. The solutions to the equation \(\sin{x} = 0.5\) are: \(x\) = -330°, -210°, 30° and 150°. Draw the horizontal line \(y = 0.75\).
