Explanation / Answer

as per chegg guide lines I am working first problem, please post remaining questions in the next post

resolve force in to components

Ax= 26.6 N cos 30 i = 23.03 N i

Ay = 26.6 N sin 30 = 13.3 N j

Bx = 2 ( 26.6 N) cos 45 = 37.6 i

By =  2 ( 26.6 N) sin 45 = 37.6 j

A- B=  (23.03 N i+ 13.3 N j)-(37.6 i+37.6 j)

=-14.58 N -24.3 N j

magnitude of A- B

mod A- B = sqrt ( -14.58062 + (-24.3)^2

= 28.33 N
