Answer is 6

Step-by-step explanation:

Use Trigonometry to do this equation

Sin30° = $\frac{n}{12}$

Multiply both sides by 12

12Sin30° = n

Then put the values into a scientific calculator

12Sin30° = n

Answer:

n = 6 $\sqrt{3}$

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin30° = $\frac{\sqrt{3} }{2}$ , then

sin30° = $\frac{opposite}{hypotenuse}$ = $\frac{n}{12}$ = $\frac{\sqrt{3} }{2}$ ( cross- multiply )

2n = 12 $\sqrt{3}$ ( divide both sides by 2 )

n = 6 $\sqrt{3}$
