It is called a complex number.
Answer:
Adjacent, x = 100
Step-by-step explanation:
80 and x are on a straight line. Straight lines = 180 degrees. 180 - 80 = x
Vertical angles are opposite of each other, not next to each other.
Answer:
6,8
Step-by-step explanation:
Answer:
y=-4/23
im not sure i didn't check (might be wrong)
Step-by-step explanation:
4x - 5y = -28
-3x - 2y = 10
then make x the same
So
12x-15y=-84
-12x-8y=80
then its left with
-23y=-4
y=-4/23
find x by entering y into -3x - 2y = 10 and solving
