A $218-16$ man is climbing up a ladder to change the garage door sensor$.$ He suddenly stops because the ladder feels as its on the verge of slipping. What is the incline of the ladder $\backslash (\backslash$theta $\backslash )$ if the coefficient of the static friction between the bottom the ladder pad $\backslash ($ A $\backslash )$ and the ground is $\backslash (\backslash$mu$=\mathrm{.}6\backslash ).$ The center of the man is at point G $.$ The weight of the ladder is not important.

I've submitted this question that I made twice already and got $2$ different answers. Someone please help.

Forst answer was $75$ degrees, second was $38\mathrm{.}7$
