³Activité

Calculez la mesure de l'angle A du triangle rectangle ci-dessous. Calculez ensuite la

mesure de l'angle B et la longueur de l'hypoténuse c. Les longueurs sont exprimées en

mètres. Arrondissez le résultat à une décimale près.

Rappel :

tan A =

donc: m±A = tan-1

( )

m±A + m±B + 90Ä= 180Ä

donc: m±B = 90Ä-m±A
