In , if 3= 4=6, calculate, and .

Answer :

=80°, =60°, =40°


Let 3= 4=6 = a


Therefore,


A = a/3, B = a/4, C = a/6 ____________________ (i)


A + B + C = 180° [Sum of angles]


a/3 + a/4 + a/6 = 180°


9a/12 = 180°


a = 240°


A = a/3 = 240° /3 = 80°


B = a/4 = 240° /4 = 60°


C = a/6 = 240° /6 = 40°
