What is the measure of angle A ?
what is the measure of angle B ?

Step-by-step explanation:

Notice that buy construction of a parallelogram,the angles and must equal each other. Then, based on the info given,  we can write the following equation:

Then, angle =  which is also equal to angle B

and since the addition of all internal angles of the parallelogram must equal , then:

and therefore, since and  must be equal, then:

umumumumum

im not sure

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
