Question

Find the value of each variable using sine and cosine. Round your answers to the nearest tenth.

Answer 1

x ≈ 9.5 , y ≈ 15.3

Explanation:

sin32° =
`(opposite)/(hypotenuse)` =
`(x)/(18)` ( multiply both sides by 18 )

18 × sin32° = x , then

x ≈ 9.5 ( to the nearest tenth )

cos32° =
`(adjacent)/(hypotenuse)` =
`(y)/(18)` ( multiply both sides by 18 )

18 × cos32° = y , then

y ≈ 15.3 ( to the nearest tenth )
