Angle A = Angle B+63, Angle C = Angle B - 18

Angle A +Angle B + Angle C = 180
==> (angle B+63) + angle B + (angle B - 18) = 180
   OR 3 x angle B = 180 - 63 + 18 = 135
  OR angle B = 135 / 3 = 45

Angle A = Angle B+63, Angle C = Angle B - 18
Angle A +Angle B + Angle C = 180
(Angle B+63) + Angle B + (Angle B - 18) = 180
3 × Angle B = 180 - 63 + 18 = 135
Angle B = 135 / 3
Angle B = 45
