Solution

Use standard Trigonometric angles
We know that,
$\sin 30 ° = \frac{1}{2}$
The given equation is,
$\sin x = \frac{1}{2}$
$\Rightarrow \sin x = \sin 30 °$ $[∵ \sin 30 ° = \frac{1}{2}]$
Comparing both sides, we get, $x = 30 °$
Hence, the value of $x$ using the Trigonometric standard angle table is $30 °$ .
