Question

can anyone find x, y and z​

Answer 1

(b) DC||AE...... So, angle C = 80°
and angle DAC= 30°= angle ACB
therefore angle ACB = y=30°
And angle AND = 80°-30°
=50°
by alternate interior angle z=50°
Now,
angle ( DAC + ACD+ADC) =180°
30°+50°+ y =180°
Therefore y =180°- 80°
y = 100°
(b) in a parallelogram opposite angles are equal.
Therefore.,
Angle (A=C) and
Angle ( B=D).....
So, Angle C=100
and also.....the sum of corresponding
angles are 180°
therefore..... Angle(B=D=80°)
