Step-by-step explanation:

It is given that the angle of triangle are in the ratio 2 : 3 : 4. ... According to the angle sum property, the sum of interior angles of a triangle is 180 degree. The value of x is 20. Therefore the angles of triangle are 40, 60 and 80.

Answer 2

lets take 2=2x,3=3x,4=4x

2x+3x+4x= 180⁰

9x=180⁰

x=180⁰/9

x=20

2x= 40⁰

3x= 60⁰

4x= 80⁰
