Question

Help!! How do I solve this

Answer 1

The answer for this question is Option B : 12.28

Answer 2

Answer:

B

Step-by-step explanation:

Using the sine ratio in the right triangle

sin17° = $\frac{opposite}{hypotenuse}$ = $\frac{AC}{AB}$ = $\frac{AC}{42}$ ( multiply both sides by 42 )

42 × sin17° = AC then

AC ≈ 12.28 ( to 2 dec.places ) → B
