Question

I need help rlly bad I have no idea what’s the answer plsss help me!!!

Answer 1

Answer is 6

Explanation:

Use Trigonometry to do this equation

Sin30° =
`(n)/(12)`

Multiply both sides by 12

12Sin30° = n

Then put the values into a scientific calculator

12Sin30° = n

6 = n

Answer 2

n = 6
`√(3)`

Explanation:

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

sin30° =
`(√(3) )/(2)` , then

sin30° =
`(opposite)/(hypotenuse)` =
`(n)/(12)` =
`(√(3) )/(2)` ( cross- multiply )

2n = 12
`√(3)` ( divide both sides by 2 )

n = 6
`√(3)`
