Answer:
[tex]m\angle A=98^o[/tex]
Step-by-step explanation:
we know that
In a parallelogram opposite angles are congruent and consecutive angls are supplementary
In this problem
we have the parallelogram ABCD
so
[tex]m\angle A=m\angle C[/tex] ----> by opposite angles
[tex]m\angle B=m\angle D[/tex] --> by opposite angles
and
[tex]m\angle A+m\angle B=180^o[/tex] ----> by consecutive angles
[tex]m\angle B+m\angle C=180^o[/tex] ----> by consecutive angles
we have
[tex]m\angle C=98^o[/tex]
therefore
[tex]m\angle A=98^o[/tex]
