Question

plz solve it !!!! guyz i cant do it

Answer 1

(1)

Fig. is a Parallelogram. So

x=100°( opposite angles of a Parallelogram are equal.)
z=180°-100°=80°( Adjacent Angles of a Parallelogram form A linear Pair.)

(2)

It is also a Parallelogram.

Diagonals of a Parallelogram Bisect each other.

So.
20=y+7( its quite Hard to read. Forgive if numericals are different)
→y=20-7=13

and
x+y=16.
→x+13=16.
→x=16-13=3.

Hope it Helps...

Forgive if the numericals Are wrong...
