Question

Find the value of x. Round to the nearest tenth.

Answer 1

x ≈ 55.6

Explanation:

Using the sine ratio in the right triangle

sin20° =
`(opposite)/(hypotenuse)` =
`(19)/(x)` ( multiply both sides by x )

x × sin20° = 19 ( divide both sides by sin20° )

x =
`(19)/(sin20)` ≈ 55.6 ( to the nearest tenth )
