Question

Solve for x. Round to the nearest tenth, if necessary. 1.8 & x

Answer 1

x ≈ 1.4

Explanation:

Using the sine ratio in the right triangle

sin50° =
`(opposite)/(hypotenuse)` =
`(RS)/(RT)` =
`(x)/(1.8)` ( multiply both sides by 1.8 )

1.8 × sin50° = x , then

x ≈ 1.4 ( to the nearest tenth )
