Question

Whuts the answer to this math equation

Answer 1

x = 14

Explanation:

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

cos30° =
`(√(3) )/(2)` , then

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

x ×
`√(3)` = 14
`√(3)` ( divide both sides by
`√(3)` )

x = 14
