Answer:
Quadrant I and quadrant IV
Step-by-step explanation:
Given that cos x< 0
x < arccos 0
x < 90degres
Since cos s positive in the first and 4th quadrant, hence the angle lies in the Quadrant I and quadrant IV
Answer:
Step-by-step explanation:
Begin by filling in x as -2 and y as √12 in the given expression:
. Work inside the parenthesis first and deal with those exponents:
(-2)³ is the same as (-2)(-2)(-2) which is -8;
(√12)² is the same as (√12)(√12) which is √144 which is 12.
Filling those simplifications in:

< 1 and < 4 are alternate interior angles
The second one is the answer
