Respuesta :

we have that
sec²x - 2 = tan²x--------> equation 1

and we know
identity-----------> tan²x=sec²x-1------------> equation 2

I substitute 2 in 1
sec²x - 2 = sec²x-1----------> -2=-1---------> no solution

the answer is the option a) No solution
The answer is no solution.
Explanation:
sec²x - 2 = tan²x
tan²x=sec²x-1
sec²x - 2 = sec²x-1
 -2=-1

there is no solution
