Answer:
obtuse (anything above 90* is obtuse)
Step-by-step explanation:
I believe its additive Inverse Property
Add each term and divide it by 2.
5+7 = 12
12/2 = 6
-2 + 6 = 4
4/2 = 2, then add the i back on to get 2i.
The midpoint is 6 + 2i
the answer is supposed to be 132 at the most of a
for b it is 165
