Answer:

[tex]\dfrac{1}{2}[/tex]

Step-by-step explanation:

[tex]sin \theta =\dfrac{Opposite}{Hypotenuse}[/tex]

30 degrees is a special angle and its trigonometric ratios can be obtained from the 30-60-90 Special triangle.

Note: The special triangle is an equilateral triangle bisected along its altitude and Pythagoras Theorem has been used to obtain the length of the altitude in surd form.

Therefore, from the Special triangle attached:

[tex]sin 30^0 =\dfrac{1}{2}[/tex]
