Answer 1

Answer:

x=100°

x+A=200°

as we know that sum of angles made in parallelogram is 360°

if x + A =200°

then other two say z and other one makes 180°(360°-200°=160°=160/2=80°)

z+y=180°( angle lie on the same plane)

80°+y=180°

y=100°

here x=100°,y=100°,z=80°

so, correct is 100°,100°,80°

Answer 2

SOLUTION -

GIVEN -
Figure ABCD is parallelogram
Angle A = 100 degree

TO FIND -
Angle x , y , z = ?

1) Angle (x)

We know that , The opposite angles of a parallelogram are equal.

Hence , angle C =  angle A
Angle C = 100 degree
Therefore x = 100 degree

2) Angle (y)

We know that , Congruent angles are equal.
Hence , Angle Y = Angle X (congruent angles)
Therefore y = 100 degree

3) Angle (z)

We know that , sum of the supplementary angle is 180 degree .
Hence , angle y + angle z = 180
                    100 + angle z = 180
                              angle z = 80 degree
Therefore z = 80 degree

THEREFORE OPTION NUMBER (B) IS CORRECT .
