Question

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

Answer 1

Answer:

Let take angles of triangle as 2x,3x and 4x.

<1+<2+<3 =180° (Angle sum property of triangle)

2x+3x+4x =180°

9x=180°

x=180°/9

x=20°

<1=2x

=2×20°

=40°

<2=3x

=3×20°

=60°

<3=4x

=4×20°

=80°

Hence,the value of angles are 40°,60° and 180°.

Answer 2

2x+3x+4x=180°

9x=180°

x=180/9

x=20

So,

2×x=2×20=40

3×x=3×20=60

4×x=4×20=80
