Help please i need help

Answer 1

XZ ≈ 14.4 cm

Explanation:

Using the cosine ratio in the right triangle, that is

cos29° =
`(adjacent)/(hypotenuse)` =
`(YZ)/(XZ)` =
`(12.6)/(XZ)` ( multiply both sides by XZ )

XZ × cos29° = 12.6 ( divide both sides by cos29° )

XZ =
`(12.6)/(cos29)` ≈ 14.4 cm ( to 3 significant figures )
