Answer 2

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
