Answer:
[tex]\:x=55^{\circ \:\:}[/tex]
Therefore, option 'b' is correct.
Step-by-step explanation:
Let x be the angle
determining the [tex]\tan ^{-1}\left(1.4281\:\right)[/tex]
[tex]\:\tan \:x\:=1.4281\:[/tex]
[tex]x=\tan ^{-1}\left(1.4281\:\right)[/tex]
[tex]\:x=55^{\circ \:\:}[/tex]
Therefore, option 'b' is correct.
