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! :)

Answer:
The absolute error of the measurement is 0.25 inches
Step-by-step explanation:
we know that
The absolute error of a measurement is equal to one half the unit of measure.
In this problem we have
7.5 inches
The measurement is given by 0.5 inches
So
the absolute error of this measurement is
Therefore
the exact measurement could be between
7.5 (+/-) 0.25 in
That is, between 7.25 in and 7.75 in
