Answer 1

Step-by-step explanation:

$let \: 3a = 4b = 6c = x \\ a = \frac{x}{3} \\ b = \frac{x}{4} \\ c = \frac{x}{6} \\ since \: sum \: of \: all \: angle \: of \: a \: triangle = 180 \\ \frac{x}{3} + \frac{x}{4} + \frac{x}{6} = 180 \\ \frac{4x + 3x + 2x}{12} = 180 \\ \frac{9x}{12} = 180 \\ x = 180 \times \frac{12}{9} \\ x = 240 \\ a = \frac{240}{3} \\ a = 80 \\ b = \frac{240}{4} \\ b = 60 \\ c = \frac{240}{6} \\ c = 40$

hope it helps...........
