Answer:
there is no mistake.
Step-by-step explanation:
the steps are all correct.
it cant be 'they should be divided' since that's not how it works.
it cant be 'tan 68 should be cos 68' since for cos we need [tex]\frac{adjacent}{hypotenuses}[/tex]
and since for tan it is [tex]\frac{opposite}{adjacent}[/tex] it cant be[tex]\frac{14}{x}[/tex]
