Can someone me with this , i would really appreciate it, you!
(geometry)

  a.  B

  b.  4

  c.  BD

Step-by-step explanation:

a. Point A is at -7; point D is at +1. The distance between these points is ...

  1 -(-7) = 8

The midpoint will be 8/2 = 4 units from either end so will be at ...

  A +4 = -7 +4 = -3

or

  D -4 = 1 -4 = -3

The point located at -3 is point B, the midpoint of AD.

__

b. Having done the above calculations, we know that segment AB is 4 units long.

__

c. We also know that segment BD is 4 units long. That is because the midpoint divides a segment into two equal parts.

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
