If sin θ = 1/2, then θ equals:

To find the value of $\theta$ given $\sin \theta = 1/2$, we refer to the trigonometric ratios of special angles (30°, 45°, and 60°). 1. **Recall the definition**: In a right-angled triangle, $\sin \theta = \frac{\text{Opposite}}{\text{Hypotenuse}}$. 2. **Special Triangle Analysis**: Consider a $30^\circ-60^\circ-90^\circ$ triangle. In this triangle, if the hypotenuse is $2$, the side opposite to the $30^\circ$ angle is $1$. 3. **Applying the ratio**: $$\sin 30^\circ = \frac{1}{2}$$ 4. **Comparison**: Since the problem states $\sin \theta = 1/2$, by comparing this to our known values, we conclude that $\theta = 30^\circ$. Therefore, the correct option is **D**.
