Question

Help!! How do I solve this

Answer 1

B

Explanation:

Using the sine ratio in the right triangle

sin17° =
`(opposite)/(hypotenuse)` =
`(AC)/(AB)` =
`(AC)/(42)` ( multiply both sides by 42 )

42 × sin17° = AC then

AC ≈ 12.28 ( to 2 dec.places ) → B

Answer 2

The answer for this question is Option B : 12.28
