Question

help me answer this trignometry question. the final answer is actually is 18.3 .but i get something else.​

Answer 1

y ≈ 18.3

Explanation:

Using the sine ratio in the right triangle

sin41° =
`(opposite)/(hypotenuse)` =
`(12)/(y)` ( multiply both sides by y )

y × sin41° = 12 ( divide both sides by sin41° )

y =
`(12)/(sin41)` ≈ 18.3 ( to 1 dec. place )
