Answer:
[tex]y=21.3\text{ }[/tex]
Step-by-step explanation:
To find y, use trigonometric ratios or relationships, which are represented by the following diagram and equations:
Use the sin ratio to find y:
[tex]\begin{gathered} \sin (80)=\frac{21}{y} \\ y=\frac{21}{\sin (80)} \\ y=21.32\text{ } \\ \text{ Rounding to the nearest tenth:} \\ y=21.3\text{ } \end{gathered}[/tex]
