Question

1. Verify the following for the values of x and y given besides them.
a.Commutative property; x= - 4, 5
b. Associative property; x = -10, y = 7, a = -6
Distributive property; x = -42, y = 51, z = 49
C.​

Answer 1

Answer:

Step-by-step explanation:

x+50

∘

=180

∘

(Linear pair)

⇒x=130

∘

Also, y=130

∘

(Vertically opposite)

Now, x=y=130

∘

(Alternate interior angles)

Alternate interior angles are equal.

∴AB∥CD.

Answer 2

you may varify it by putting values
