Question

Find the measure of x.

10
х
20°
x = [? ]
Round your answer to the nearest hundredth.

Answer 1

x ≈ 3.42

Explanation:

Using the sine ratio in the right triangle

sin20° =
`(opposite)/(hypotenuse)` =
`(x)/(10)` ( multiply both sides by 10 )

10 × sin20° = x , then

x ≈ 3.42 ( to the nearest hundredth )
