AB || DC we have
<A + <D = 180°
55°+ <D = 180°
<D = 180°-55°
= 125°
also,
<B + <C = 180°
70° + <C = 180 °
<C = 180°-70°
= 110°

Answer:
the other two angles will be 50° and 70°.
angle A + angle D = 180°
angle D + 130° = 180°
angle D = 50°
angle B + angle C = 180°
angle C + 110° = 180°
angle C = 70°
