Question

if the angles of a triangle are in the ratio 2:3:4. Find all the angles of a

triangle and classify the triangle in two different ways.​

Answer 1

Answer:

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

→ let common ratio be x

∴ Angle are 2x, 3x and 4x

∴ 2x+3x4x=180 degree

∴ 9x=180 degree

∴ x= 180 degree / 9 =20 degree

∴ Angle are 40 degree , 60 degree , 80 degree
