Question

if a triangle angles are in ratio 2 ratio 4 ratio 3 find the measure of each angle

Answer 1

2x + 4x + 3x = 180
9x = 180
x = 20
A = 40
B = 80
C = 60
thanks...

Answer 2

the sum of all angles of a triangle is 180° . then let the angles be x therefore 2x , 4x,3x.
2x+3x+4x=180°
9x=180
x=180/9
x=20
therefore 2x=20*2=40
3x=20*3=60
4x=4*20=80
