Question

if the angles of a triangle are in the ratio 2 : 3 : 4 , find the angles​

Answer 1

Step-by-step explanation:

ANSWER

Let common ratio be 2x,3x and 4x

→ let common ratio be x

∴ Angle are 2x, 3x and 4x

∴ 2x+3x4x=180

o

∴ 9x=180

Answer 2

Step-by-step explanation:

Let us suppose the Angles in Ratio be:-

-->2x+3x+4x=180

-->9x=180

x=180/9

x=20

Hence,

Angle first =20×2=40°

Angle second=20×3=60°

Angle third=20×4=80

Hence the side will be=40°,60°and 80°.
