A 604N weight held by two cables. The left hand cable had tension (T2) and makes an angle of 45 degrees with the ceiling. the right hand cable had tension T1 and makes an angle of 53 degrees with the ceiling.

T1 = 457 N; T2 = 389 N.
You can prove this to your satisfaction by substituting these figures in the following equations:
T1 sin 53° + T2 sin 45° = 640
T1 cos 53° − T2 cos 45° = 0
By the way, this same set of equations was used to solve the problem.

T(2)cos45=T(1)cos53
T(2)sin45+T(1)sin53 =604 N , as cos45=sin45 ,therefore
T(1)cos53+T(1)sin53=604 N
T(1){0.6+0.8}=604 N hence T(1)=604/1.4=445 N
T(2)=380N
