Question

If the angles of a triangle are in the ratio 2:3:4,find other angles.

Answer 1

Answer:

2x + 3x + 4x = 180° (ASP)

9x = 180°

x = 180/9

x = 20°

2x = 40°

3x = 60°

4x = 80°

Answer 2

Given,
Angle a=2x,b=3x and c= 4x


Now,

2x+3x+4x=180 .......(since sum of all
angles of a
Triangle is 180)

9x=180

X=180/9

X=20


Now,
Angles of a triangle is


2x=2*20=40,

3x=3*20=60,&

4x=4*20=80


Therefore,the angles of a triangle is 40,60,80.
