Question

the ratio of the measure of the three of a triangle is 2:3:4: .the measure of the largest angle is:-

​

Answer 1

Answer:

let the angle be x so that

2x +3x+4x = 180° (Angel sum property)

9x = 180°

x = 20°

2x = 2*20 = 40°

3x = 3*20 = 60°

4x = 4*20 = 80°

Answer 2

Answer:

$\large\boxed{\sf{80\degree}}$

Step-by-step explanation:

According to question,

Ratio of measure of angles of a triangle is 2:3:4

.°.Let the angles of the triangle be 2x , 3x and 4x respectively.

By angle sum property of a triangle,

=> 2x + 3x + 4x = 180°

=> 9x = 180°

=> x = 180/9

=> x = 20

.°. Angles are 40°, 60° and 80°

Hence, largest angle is of 80°
