Can someone help me here? :(

OpenStudy (anonymous):

\[\tan x = 31\]

OpenStudy (anonymous):

take tan^-1 of both sides

OpenStudy (anonymous):

I'm still rather kinda confused though...

OpenStudy (anonymous):

So instead of the x, it's just a 1?

OpenStudy (anonymous):

\[x=\tan ^{-1}(31)\]

OpenStudy (anonymous):

the tan inverse just cancels out the tan

OpenStudy (anonymous):

the answer should be 1.54 rad
