Question

In the following figure, the value of x is____

​Note: Round your answer to the nearest tenth

Answer 1

x ≈ 8.3 ( to the nearest tenth )

Explanation:

Using the cosine ratio in the right triangle

cos41° =
`(adjacent)/(hypotenuse)` =
`(BC)/(AB)` =
`(x)/(11)`

Multiply both sides by 11

11 × cos41° = x, thus

x ≈ 8.3
