Question

the angle of a triangle are in ratio 2:3:4 find the angle
​

Answer 1

Answer :-

Given :-

Ratio is 2:3:4

To find :-

Value of each angle

Solution :-

$\pink{\boxed{\sf{Sum\: of\: all\: angles\: of\: triangle\: is\: 180°}}}$

Let,

2:3:4 be,

2x,3x,4x

Therefore,

2x+3x+4x = 180°

9x = 180°

$x = \frac{180}{9}$

$\large\orange{\boxed{\sf{Value\: of\: x=20°}}}$

Value of 2x = 40°

Value of 3x = 60°

Value of 4x = 80°

Hope it helps..

Answer 2

Step-by-step explanation:

Given:-

Ratio = 2:3:4

Solution:-

The sum of all angles of triangle is 180°

Let be,

2:3:4 as 2x,3x,4x

Then,

===>2x+3x+4x = 180°

===>9x=180°

===>x=180/90

===>x = 20°

Hence,2x=40°,3x=60°&4x=80°.
