Postulate: statement that is assumed to be true w/out proof
Theorem: true statement that can be proven
5x+2x+12=180
consecutive angle are supplementary
7x+12=180
7x=168
x=24
angle D=5x opposite angle are congruent
5x=120
Angle d=120
Hope it help:)
Answer:
The correct option is (D).
Step-by-step explanation:
The two expressions are:

On simplifying both the expressions we get:

Compute the value of both expressions for <em>x</em> = 2 as follows:

The value of both expressions are same for <em>x</em> = 2.
Thus, the correct option is:
"They are equivalent because when x = 2, the two expressions have the same value."
