Answer:
[tex]\large{x=7.4438\ cm\approx7.4\ cm}[/tex]
Step-by-step explanation:
Use tangent:
[tex]tangent=\dfrac{opposite}{adjacent}[/tex]
We have:
[tex]\alpha=28^o,\ opposite=x,\ adjacent=14\ cm[/tex]
[tex]\tan28^o\approx0.5317[/tex]
Substitute:
[tex]\dfrac{x}{14}=0.5317[/tex] multiply both sides by 14
[tex]x=7.4438\ cm[/tex]
