I guess that the problem is about the tensions of the strings, not their lenghts...

The sum of the horizontal components is zero, then

T1 cos(60) - T2 cos(53) = 0

T1 = (cos(53)/cos(60)) T2 = 1.2036 T2

On the other hand,

T1 sin(60) + T2 sin(53) = 8

or

T2( tan(60) cos(53) + sin(53)) = 8 = 4.3454 T2

T2 = 13.6647 Kg (or 134.0504 N)
T1 = 5.2303 Kg (or 51.3093 N)

T1/sin60 = T2/sin53

use your calc to do the rest
