12,351 ~ 12,400 I rounded 12,351 to 12,400 because when there is 5 when you round,the hundred goes up.

Answer:
6 : 8
Step-by-step explanation:
It means coming right after the other
example, consecutive integers are like 1,2,3,4,5, etc
consecutive even integers are 2,4,6,8 etc
consecutive odd integers are 1,3,5,7, etc
you get the point
The equation is equivalent to 1/cos(2x)-2=sin(2x)/cos(2x). Make the denominator cos(2x) for all terms, we get 1-2cos(2x)=sin(2x). Since cos^2(2x)+sin^2(2x)=1, let cos(2x)=a, substitute sin(2x) by +-\sqrt(1-a^2), and solve the equation with only one variable a. We get a=4/5 or 0, but cos(2x) cannot be 0, otherwise sec(2x) is undefined. 2x=36.9 degrees, so x=18.9 degrees approximately.
