oh sorry I did try taking moments in both point 1 and point 2 and turned out with nothing.
Taking moment at point 1.
M1=-(3(150))+Fn2(10)
Taking moment at point 2
M2=-(Fn1(10)+(7(150))
Taking moment at where the person is at
M3=-Fn1(3)+Fn2(7)
From there on I'm not sure what to do
ahh found it

The Attempt at a Solution
Sum of Fx= Fn1 - Ffr2=0 Fn1=Ffr2
Sum of...
anyways naming the point of where ladder touching the wall 1 and the part where the ladder touches the ground 2 I have
Fn1 will the wall's force on the ladder and Fn2 will be the ground's force on the ladder. Ffr1 is friction of where 1 is and Ffr2 is friction force of where 2 is.
Sum of Fx=...
