What is the measure of angle A ?<br> what is the measure of angle B ?
lesya692 [45]

Answer:

\angle\,A=72^o\\\angle\,B=108^o

Step-by-step explanation:

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

3\,y+27^o=5\,y-3^o\\27^o+3^o=5\,y-3\,y\\30^o=2\,y\\y=15^o

Then, angle \angle \,A =5\,(15^o)-3^o=72^o  which is also equal to angle B

and since the addition of all internal angles of the parallelogram must equal 360^o , then:

B+D=360^o-72^o-72^o=216^o

and therefore, since \angle \,B and \angle \,D  must be equal, then:

\angle\,B=\frac{216^o}{2} =108^o
