The given pair of angles doesn't form any special pair of angles provided in the options , hence the Correct choice is none of these.
60
D>0, there are 2 distinct real roots
Explanation:
3x2+6x−2=0
a=3,b=6,c=−2
The formula for discriminant is b2−4acSubstitute the given values.
b2−4ac
(6)2−4(3)(−2)
=60
therefore, D>0, there are 2 distinct real roots
Answer:
-270 to -360 degrees I quadrant
And for this case since -300° is between -270 to -360 degrees we can conclude that this angle is in the I quadrant
Step-by-step explanation:
For this case we can solve this problem taking in count the following rule when we have negative angles:
0 to -90 degrees IV quadrant
-90 to -180 degrees III quadrant
-180 to -270 degrees II quadrant
-270 to -360 degrees I quadrant
And for this case since -300° is between -270 to -360 degrees we can conclude that this angle is in the I quadrant
