Question

Using a trigonometric ratio to find a side length in a right triangle. ROUND TO THE NEAREST TENTH ‼️ Can someone help me please❓ Thx

Answer 1

x ≈ 34.9

Explanation:

Using the sine ratio in the right triangle

sin35° =
`(opposite)/(hypotenuse)` =
`(20)/(x)`

Multiply both sides by x

x × sin35° = 20 ( divide both sides by sin35° )

x=
`(20)/(sin35)` ≈ 34.9 ( to the nearest tenth )
