Answer:
Step-by-step explanation:
<span>Simplifying
x4 + -2x3 + 6x2 + -2x = 5
Reorder the terms:
-2x + 6x2 + -2x3 + x4 = 5
Solving
-2x + 6x2 + -2x3 + x4 = 5
Solving for variable 'x'.
Reorder the terms:
-5 + -2x + 6x2 + -2x3 + x4 = 5 + -5
Combine like terms:
5 + -5 = 0
-5 + -2x + 6x2 + -2x3 + x4 = </span>0

Turn (7 1/2) into an improper fraction (15/2)
Find the lowest common denominator (4)
convert 15/2 to 30/4
(30/4) / (3/4)
Add 720 degrees (which represents two full revolutions around the center) to -800. Result: -80 degrees. This angle is in Quadrant IV.
Subtracting 80 from 360 will give you a positive angle co-terminal with -800 deg. 360 - 80 = ?
