Question

2. Consider the following parallelograms. Find the values of the unknowns
x,y,z​

Answer 1

Answer:

HELLO

Step-by-step explanation:

B + D= 180°( linear pair )

100+y =180 °

y= 80°

x=100 corresponding angles

now z= 80°

Answer 2

let angle B=100°

angle C=x

angle A=z

angle D=y

angle B=angle D

100°=100°

angle B+angle C=180° <co interior angle >

100°+x=180°

x=180°-100°=80°

x=80°

angle C=angle A

x=z

80°=80°

x=80°

y=100°

z=80°
