Answer:

fourth option

Explanation:

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

sin60° =
(√(3) )/(2) , cos60° =
(1)/(2) , then

sin60° =
(opposite)/(hypotenuse) =
(x)/(4√(2) ) =
(√(3) )/(2) ( cross- multiply )

2x = 4
√(6) ( divide both sides by 2 )

x = 2
√(6)

---------------------------------------------------------

cos60° =
(adjacent)/(hypotenuse) =
(y)/(4√(2) ) =
(1)/(2) ( cross- multiply )

2y = 4
√(2) ( divide both sides by 2 )

y = 2
√(2)
