Question

Pls if you can help

Answer 1

x ≈ 8.4

Explanation:

10

using the cosine ratio in the right triangle

cos64° =
`(adjacent)/(hypotenuse)` =
`(MN)/(LN)` =
`(3.7)/(X)` ( multiply both sides by x )

x × cos64° = 3.7 ( divide both sides by cos64° )

x =
`(3.7)/(cos64)` ≈ 8.4 ( to the nearest tenth )
