ayudenme porfavor necesito urgente este punto​

Answer 1

Respuesta:

x = 0° ∨ x = 45°

Explicación paso a paso:

sec²x = tang²x +1

sec²x + tangx = 1

(tang²x +1) + tangx = 1

tang²x  + 1  + tangx -1 = 0

tang²x + tangx  = 0

tangx (tangx +1) = 0

tangx = 0 ∨ tangx +1 = 0

tangx = 0 ∨ tangx = -1

x = 0° ∨ x = 315°
