A:

HI,

Angle A + Angle B + Angle C = 180

Now, Angle A + Angle B = 84

Thus, 84 + Angle C = 180

Angle C = 180 - 84 = 96

Angle B + Angle C = 146

Angle B + 96 = 146

Angle B = 146 - 96 = 50

Angle A + Angle B = 84

Angle A + 50 = 84

Angle A = 84 - 50 = 34

Thus, Angle A = 34, Angle B = 50 and Angle C = 96
