Question

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

Answer 1

Answer:

Step-by-step explanation:

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

According to the question,2x+3x+4x=180

=> 9x=180

=>x=180/9=20

Therefore,2x=2×20=40

3x=3×20=60

4x =4×20=80

Hope it helps

Thanks

Answer 2

question :-

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

solution :-

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

2x+3x+4x=180 ( angle sum property of triangle)

9x = 180

x= 180/9

x= 20°

so, the angles of triangle are :-

2x => 2×20 = 40°

3x => 3× 20 = 60°

4x => 4× 20 = 80°

answer:-

the angles of triangle are 40°,60°,80°
