Since A+B+C=pi

=> A+B =pi-C = pi-pi/3 = 2pi/3.....[ the angles should satisfy this condition]

Now we have ,

a/b = tan5pi/12

=> sinA/sinB = tan5pi/12

=> sinA/sinB = ( sin5pi/12 )/( cos5pi/12 )

=> sinA/sinB = ( sin5pi/12 )/( sinpi/12 )     [ cos5pi/12 = sinpi/12]

=> sinA/sinB = ( sin7pi/12 )/( sinpi/12 )     [ sin5pi/12 = sin7pi/12]

=> on comparing both sides we find that A=7pi/12 and B=pi/12 which satisfies the  condition that  A+B  = 2pi/3

Hence ,
A=7pi/12
B=pi/12
C=pi/3
