Transcribed Image Text:**Consider this right triangle.**
The diagram shows a right triangle \( \triangle ABC \), where angle \( \angle ACB \) is the right angle (90°). The hypotenuse is labeled \( AB \), the side opposite the 57° angle (at vertex \( B \)) is labeled \( AC \), and the adjacent side to the 57° angle (at vertex \( B \)) is labeled \( CB \).
In the triangle:
- \( \angle ABC = 57^\circ \)
- The length of side \( CB \) is 9 units.
**Enter the length of side \( AC \), to the nearest tenth.**
