Answer:
A/Q 3A=4B=6C
let 3A=4B=6C=K
let's write every angle with respect to angle K
angle A = K/3
angle B = K/4
angle C = K/6
now we know sum of all angle of triangle is 180
therefore
K/3 + K/4 + K/6 = 180
taking LCM 12
(4K + 3K + 2K)÷12 = 180
9K/ 12= 180
9K= 180×12
K= (180×12)÷9
K=240
angle A= K/3= 80
angle B= K/4= 60
angle C= K/6= 40
