Question

If the angles of a triangle are in the ratio 3:4:5, then find out the value of

each angle.​

Answer 1

Answer:

let the common multiple of the ratios be 'x'

therefore

3x + 4x + 5x = 180°. (angles of triangle add up to 180°)

12x = 180

x =180/12

x=15

angle 1 =3x=3(15)=45°

angle 2=4x=4(15)=60

angle 3=5x=5(15)= 75°

hope it helps

Answer 2

so ,

let the number be x

3x+4x+5x = 180

= x = 12×( by adding 3 4 and 5 )

12×=180

180/12 = 15

x = 15

15 × 3 = 45

15 × 4 = 60

15 × 5 = 75

ans = 45 , 60 , 75

lets crosscheck

45 +60+75= 180
