Please help with these questions thank you very much.

Answer 1

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.

$7x+7=112$

Subtract both sides by 7

$7x=105$

Divide both sides by 7

$x=15$

The second choice is your answer. Have an awesome day! :)

Answer 2

1 is D
2 is
7x + 7 = 112
7x = 105
x = 15 (B)
