Question

Progress
Solve for x. Round to the nearest tenth, if necessary

Answer 1

x ≈ 1.1

Explanation:

using the cosine ratio in the right triangle

cos41° =
`(adjacent)/(hypotenuse)` =
`(0.8)/(x)` ( multiply both sides by x )

x × cos41° = 0.8 ( divide both sides by cos41° )

x =
`(0.8)/(cos41)` ≈ 1.1 ( to the nearest tenth )
