Question

If the angles of a triangle are in the ratio 2:3:4, determine the three

angles.​

Answer 1

Answer:

40°, 60° , 80°

Step-by-step explanation:

Let the angles be 2x,3x,4x

2x+3x+4x= 180°

9x= 180°

x= 180/9

x= 20

Now angles

2*20= 40

3*20=60

4*20=80

Angles are 40°, 60°, 80°

$\huge\red{\boxed{\blue{\mathcal{\overbrace{\underbrace{\fcolorbox{blue}{aqua}{\underline{\red{ANSWER}}}}}}}}}$

let the angles be 2x,3x and 4x.Then,

2x+3x+4x=180 (sum of all angles of a triangle =180°)

=>9x=180

=>x=180/9

=>x=20

therefore,the angles are ,

2x=2×20=40°

3x=3×20=60°

4x=4×20=80°
