Answer:

180°

Explanation:

ABCD is a parallelogram.

Measures of the opposite angles of a parallelogram are equal. Here
\angle A, \:\: \angle C \: \: and\:\: \angle B, \:\: \angle D are opposite angles.


\therefore m\angle A = m\angle C = 110\degree


\& \:m\angle B = m\angle D = 70\degree


m\angle A + m\angle B =110\degree + 70\degree


m\angle A + m\angle B =180\degree
