Answer:

2nd option

Explanation:

using the cosine and sine ratios in the right triangle and the exact values

cos30° =
(√(3) )/(2) and sin30° =
(1)/(2) , then

cos30° =
(adjacent)/(hypotenuse) =
(x)/(12√(3) ) =
(√(3) )/(2) ( cross- multiply )

2x = 12
√(3) ×
√(3) = 36 ( divide both sides by 2 )

x = 18

and

sin30° =
(opposite)/(hypotenuse) =
(y)/(12√(3) ) =
(1)/(2) ( cross- multiply )

2y = 12
√(3) ( divide both sides by 2 )

y = 6
√(3)
