Respuesta :

2 adjoining angles in a parallelogram need to equal 180 degrees

If angle A = 70, then angle B = 180 - 70 = 110 degrees.

The answer is the third choice.
all you just have to do is subtract we already know that the total is 180 degrees so 180 degree - 70 which is 110 
so 110 is your answer
hope it helps.
