This depends on your age and what language you are trying to learn really. Think about it this way, when you were born, how long did it take you to learn English (or your native tongue)?

So really there is no real definite answer because all people are different, but if I were to say, I'd say about five years...
Explanation:
Un triángulo oblicuo es cualquier triángulo que no sea un triángulo rectángulo. Podría ser un triángulo agudo (los tres ángulos del triángulo son menores que los ángulos rectos) o podría ser un triángulo obtuso (uno de los tres ángulos es mayor que un ángulo recto). En realidad, a los efectos de la trigonometría, la clase de "triángulos oblicuos" también podría incluir triángulos rectángulos. Entonces, el estudio de los triángulos oblicuos es realmente el estudio de todos los triángulos.
