Answer 1

Answer:

$\huge{\boxed{\rm{\red{Answer=80°}}}}$

Step-by-step explanation:

Given:-

The angles of a triangle ABC are in the ratio 2:3:4.

To find:-

Find the largest and smallest angle

Using formula:-

The sum of all three angles in a triangle is 180°

Solution:-

The ratio of three angles =2:3:4

Let they be 2x,3x,4x

The sum of all the three angles in a triangle=180°

=>2x+3x+4x=180°

=>9x=180°

=>x=180°/9

=>x=20°

hence,2x=2(20°)=40°

3x=3(20°)=60°

4x=4(20°)=80°

The smallest angle =40°

The largest angle=80°

Answer:-

The largest angle=80°
