Question

if the angles of a triangle ABC are in the ration 2:3:4 find the measurs of the angle A, B,C​

Answer 1

Answer:

Sum of angles of triangle = 180°

2x+3x+4x = 180°

9x = 180°

x = 20°

So, angles are A = 2×20° = 40°

B = 3×20° = 60°

C = 4× 20° = 80°

Done...

Answer 2

let

a=2x

b=3x

c=4x

and a+b+c=180°

2x+3x+4x=180°

9x=180°

x=180/9=20

so a=2x=2*20=40

b=3x=3*20=60

c=4x=4*20=80

a+b+c=180

40+60+80=180°
