Question

9. If the ratio of angles of a triangle is 2:3:4, find the measure of each angle.​

Answer 1

Step-by-step explanation:

let the ratios be 2x, 3x and 4x

then,we know that

LA +LB+LC=180°

2x+3x+4x=180°

9x=180°

x=20°

Then putting the value of x in the given ratios.. we have,

2x=20°, 3x=60° and 4x=80°

Answer 2

Step-by-step explanation:

The angels of a triangle =180

The ratio of angles of a triangle is 2:3:4

sum of the ratio =2+3+4

=9

first angel = 2/9×180

=2×20

=40

second angle=3/9×180

=3×20

=60

third angle =4/9×180

=4×20

=80

therefore the measure of each angle =40,60,80
