Question

Solve for X, Leave in simplest radical form.

Answer 1

x = 8
`√(3)`

Explanation:

using the cosine ratio in the right triangle and the exact value

cos30° =
`(√(3) )/(2)` , then

cos30° =
`(adjacent)/(hypotenuse)` =
`(x)/(16)` =
`(√(3) )/(2)` ( cross- multiply )

2x = 16
`√(3)` ( divide both sides by 2 )

x = 8
`√(3)`
