$\huge\red\star{\fcolorbox{yellow}{red}{\large{\fcolorbox{blue}{yellow}{{\fcolorbox{orange}{lime}{♛80°♛}}}}}}\pink\star$

Given:-

The ratio of the sides of the triangle is $2 : 3 : 4.$

To find :-

The largest angle.

Solution :-

Let the angle in ratio be 2x , 3x and 4x

A/Q.

The sum of all angles of a triangle is 180°.

→ 2x + 3x + 4x $&#x3d$ 180° (Angle sum property)

→9x $&#x3d$ 180

→ x $&#x3d$ 180/ 9

→ x $&#x3d$ 20°

Put the value of x,

2x $&#x3d$ 3 $&#xd7$ 20 $&#x3d$ 40°

3x $&#x3d$ 3 $&#xd7$ 20 = 60°

4x $&#x3d$ 4 $&#xd7$ 20 = 80°

hence, the largest angle is 80°.

Hope this helped!

Answer 2

Answer:

Option A is correct

2x+3x+4x=180

9x=180

x=180/9

x=20

the largest angle is 4x=4×20=80 answer
