## The Attempt at a Solution

Here is what i have done so far:

Fx = cos 45 T - Ff =ma

Fy=sin 45 T -mg+ Fn =ma

I found ff= uk * Fn = 0.5 *sin 45 +mg

fn = sin 45 +mg

Isolated for T in the x and y:

Tx = ma + Ff / cos 45 = 13.404

Ty = ma +mg - Fn / sin 45 = 83.938

found the resultant for T: sqrt( (13.404)^2 + (83.938)^2 ) = 85 N????

What am i doing wrong? i've been stuck on this for 3 +hours now with no help :(

the answer is meant to be E.
