Answer:
∠ b = 12°
Step-by-step explanation:
Complementary angles sum to 90°, thus
a + b = 90 ← substitute a = 78
78 + b = 90 ( subtract 78 from both sides )
b = 12
That is ∠ b = 12°

The answer to your question i think is b
<span>midpoint formula: (x1+x2)/2,(y1+y2)/2
For given problem:
P1=(-7,8)
P2=(x,y)
Midpoint=(-1,7)
..
(x-7)/2, (y+8)/2=(-1,7)
(x-7)/2=-1
