yes , it is possible
by the law of cosines of sides and
law of sines
now ,
using law of cosines for sides :
cos a = cos b cos c + sin b sin c cosA
cos 120° = cos 125°cos 130° + sin 125° sin 130° cosA
A = 77°93'
using law of sines:
sincsinC = sinasinA
sin130°sinC = sin120°sin77°93′
C = 60°48'
sinbsinB = sinasinA
sin125°sinB = sin120°sin77°93′
B = 68°51'
now we also can see spherical excess
E = (A+B+C) - 180°
E = (77°93' + 68°51' + 60°48' )-180°
E = 26°92'
