EXPLANATION
Given the right triangle, we know by the Pythagoras Theorem that the following relationship applies:
Tg α= opposite cathetus/adjacent cathetus
Isolating the Opposite Cathetus:
[tex]AdjacentCathetus\cdot\tan \alpha=\text{Opposite Cathetus}[/tex]
Replacing terms:
[tex]16\cdot\tan 10=x[/tex]
Switching sides:
[tex]x=16\cdot\tan 10[/tex]
Simplifying:
[tex]x=2.82[/tex]
The answer is 2.82 units
