Question 1:
The answer the last choice.
You need at least 2 points to form a line; thus, you can eliminate the second choice since it only uses 1 point.
You need at least 3 points to form a plane. You can eliminate the first and third choice because they only use 2 points to try to name the plane.
That leaves you with the last choice.
Question 2:Vertical angles are congruent. 112 and 7x+7 are vertical angles.
We can form an equation.
Subtract both sides by 7
Divide both sides by 7
The second choice is your answer. Have an awesome day! :)
