Question

Solve for indicated side. Round to the nearest hundredth.
Z=

Answer 1

z ≈ 145.62

Explanation:

using the sine ratio in the right triangle

sin18° =
`(opposite)/(hypotenuse)` =
`(45)/(z)` ( multiply both sides by z )

z × sin18° = 45 ( divide both sides by sin18° )

z =
`(45)/(sin18)` ≈ 145.62 ( to the nearest hundredth )
