The question will first read in English followed by a reading in French.

***************************************

If alpha + 2 beta = pi/4 AND tan beta = 1/3. What would tan alpha mesure?

(Keep in mind that pi/4 is the same as 45 degrees.)

Si alpha + 2 beta = pi/4 ET tan beta = 1/3. Calculer exactement tan alpha. (Gardez en tête que pi/4 est égal à 45 degrés.)
