Answer:
It is either 2 or 4, I think it might 2, kind of hard to tell. Sorry if neither of my educative guesses are correct.
Step-by-step explanation:
the correct answer is a, because a vertical angle is made of 2 intercepting lines.
The sides must be equal otherwise BC and AD wouldn't be parallel. So
12x-6 = 2x+7
10x = 13
x = 13/10 = 1.3
Answer:
a^2b(7 + 10b + 14b^2)
Use wolframalpha for math questions, or photomath!
To solve this, factor out a^2b from the expression.
