Question

1: If the angles of a triangle ABC are in the ratio
2:3:4
Find the measure of the angles ABC?​

Answer 1

Answer:

sum all angles in triangle is 180 degrees

2x+3x+4x=180

9x=180

x=20

2x=40

3x=60

4x=80

Answer 2

Answer:

Let the ratios of Angle A,B,C be X

so ratio of Angle A,B,C be 2x,3x,4x respectively

As per angle sum property,

AngleA+AngleB+AngleC=180

2x+3x+4x=180

9x=180

x=180/9

x=20

For angles,

Angle A=2x=2(20)=40

Angle B=3x=3(20)=60

Angle C=4x=4(20)=80
