Question

Ratios of angle 2,3,4 then each angle 2x,3x,4x sum angles of triangle= 180

Answer 1

Then
We know that a+b+c=180
2x+3x+4x=180
9x=180
X=180/9
X=20
2x=40
3x=60
4x=80

Answer 2

$2x + 3x + 4x = 180 \\ 9x = 180 \\ x = 180 \div 9 \\ x = 20 \\ \\ first \: angle = 2x = 40\\ second \: angle = 3x = 60\\ third \: angle = 4x = 80$
