Question

The angles of a triangle are in the ratio 2:3:4.the measurement of the greatest angle is

Answer 1

As we know that sum of all angles of triangle is 180°

_______

Let angles are :- 2x, 3x, 4x

2x +3x +4x =180

9x =180

x =180/9

x =20

Angles are :-

2×20=40°
3×20=60°
4×20=80°


Now, greatest angle => 4x =4×20=80°

I hope this will help you

Hey!!!
________________________________
●Let the angles of triangle be 2x, 3x and 4x
We know that Sum of angles of a traingle is 180°
So, ATQ
2x+ 3x+ 4x =180°
9x=180°
x=180°/9
x=20°
Hence,Measurements of angle are 2×20°, 3×20° and 4×20°=40°,60°and 80°
So,Measurement of greatest angle is 80°
