B-A =30 ==> B = 30+A
C-B = 45.
C - ( 30+ A) =45
C - A = 45+30
C - A =75.... (1)
C =75+A
===============
A+ B + C = 180
A+ 30+ A + 75+A = 180
3 A + 105 = 180
3 A = 75
A = 25 °
NOW find B - A =30 => B =55°
NOW find C - B =45 => C = 45+ 55 =100
(A,B,C) = (25,55,100)
C-B = 45.
C - ( 30+ A) =45
C - A = 45+30
C - A =75.... (1)
C =75+A
===============
A+ B + C = 180
A+ 30+ A + 75+A = 180
3 A + 105 = 180
3 A = 75
A = 25 °
NOW find B - A =30 => B =55°
NOW find C - B =45 => C = 45+ 55 =100
(A,B,C) = (25,55,100)
