Question

ABCD is a parallelogram If m C = 98 then what is m A

Answer 1

Answer:

$m\angle A=98^o$

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

$m\angle A=m\angle C$ ----> by opposite angles

$m\angle B=m\angle D$ --> by opposite angles

and

$m\angle A+m\angle B=180^o$ ----> by consecutive angles

$m\angle B+m\angle C=180^o$ ----> by consecutive angles

we have

$m\angle C=98^o$

therefore

$m\angle A=98^o$
