Question

Idk how to do this help pls

Answer 1

x ≈ 11.5

Explanation:

Since the triangle is right use the sine ratio to solve for x

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

Multiply both sides by 20

20 × sin35° = x, hence

x ≈ 11.5 ( nearest tenth )

Answer 2

Answer: x=8.56365

Explanation:

You have the angle and hypotenuse and have to find the opposite so you use sin.

Sin#=o/h

Sin35=o/20

Then I just put that into my calculator and got x= 8.56365. (I added the decimals cause idk what you need to round to)
