A triangle has an angle whose sine is equal to 1/2. The angle is larger that 43 degrees in measure. Find the exact measure (in degrees) of the angle.
Thanks!

sin 30° = ½, but if it is bigger than 43°, then just go to the secnd quadrant and look at 180° – 30° = 150°, So it is an obtuse triangle.
check: sin 150° = ½
check: sin 150° = ½
