Can someone please answer this for me? Find the measure of side a. I will give brainliest answer!

Answer:
6 m
Step-by-step explanation:
The sine of an angle is the ratio between the opposite side of the angle and the hypotenuse.
Hence, sin 30° = [tex]\frac{a}{c}[/tex]
= [tex]\frac{a}{12}[/tex]
a = 12sin30°
a = 6m
