Answer:

Let angles be x.

then,

3angleA=x

therefore angle A =x/3

4 angle B= x

therefore angle B=x/4

6angleC=x

therefore C=x/6

A/Q anglesA + angleB+ angle C =180(sun of all angles of a triangle is 180 degree).

x/3+x/4+x/6=180

lcm=12

( 4x+3x+2x) /12 =180

9x/12 =180

therefore, x=(180*12) /9

x=240

angle A=x/3=240/3

=80degree.

angle B =x/4=240/4

=60degree

angleC=x/6=240/6

=40degree.
