Answer:
Explanation:
When the angle you are given is minus, you keep on adding 360 until you get a number that is between 0 and - 360. That is the first part of the problem.
-800 + 360 = -440 That's not enough. You have to add another 360.
-440 + 360 = -80 degrees.
Rule: When you want the positive coterminal angle of an angle that is negative, Take the absolute value of the negative angle and subtract from 360. Alternately you could just add the negative angle to 360.
- 80 degrees is in the 4th quadrant. The angle that is coterminal with -80 is what you need to add to 360
x + abs(-80) = 360 Take the absolute value of -80
x + 80 = 360 Subtract 80 from both sides.
x + 80-80 = 360 - 80
x = 280
