here one external angle so we know that
Exterior angle= sum of two interor angle.

angle DAC=132°
angle BAC= 180° - 132° [By linear pair]
= 48°
exterior angle = opposites interior angles
hence, angle B + angle C = angle DAC
hence, x° + x° = 132°
= 2x° = 132°
x = 132° ÷ 2
= 71°
hence, angle A = 48°
angle B = 71°
angle C = 71°
