Get rid of cos2x by dividing both the values. So Sin2x/cos2x +3cos2x/cos2x.
Tan2x = 3
2x = -71.5 so x is -35.6
Use the quadrant method and add 360 twho the two values tou get.
Answer:
The simplified sum is 
Step-by-step explanation:
we have

For this case we have:
Represents the solution of all strict minor numbers to 2.
Represents the solution of all numbers greater than or equal to 2.
The solution set, according to the figure, is given by the union of
and
. Thus, the complete solution is given by all the real numbers.
