Question

find x y and z
please answer fast

Answer 1

Z+30°=90°
=>Z=90°-30°
=60°

Z=X(corresponding angles maybe but I don't remember the exact property)
=60°

X+Y+Z=180°
60°+Y+60°=180°
Y=180°-120°
=60°

Answer 2

If this is a parallelogram, adjacent angles add up to 180, therefore

30+z = 180-112

z= 180-30-112

z=38

Therefore x=38( opp interior angles)

And y = 112

Opposite angles of a parallelogram are equal.
