I have an equation that needs to be solved numerically.
-125=-arctan(0.25*x)-0.2*x*180/pi
I know that the answer can be approximatedto 6, according to the exams "corrected answer"
I cant solve it with pen and paper so I wonder if there is anyway to solve this in MATLAB?

est_x = fzero(fcn, 10)
producing:
est_x =
