`\cos(30°) = (16 √(3) )/(s) \\`

`( √(3) )/(2) = (16 √(3) )/(s) \\`

Inverse both sides

`(2)/( √(3) ) = (s)/(16 √(3) ) \\`

`(s)/(16 √(3) ) = (2)/( √(3) ) \\`

Multiply sides by 16√3

`16 √(3) * (s)/(16 √(3) ) = 16 √(3) * (2)/( √(3) ) \\`

`s = (2 * 16 * √(3) )/( √(3) ) \\`

`s = 32`

Thus the correct answer is Option D .
