Question

the angles of a triangle ABC are in the ratio 4:5:6 find them​

Answer 1

Answer:

let the angles be 4x,5x,and 6x

sum of all the angles of a triangle is 180°

=>4x+5x+6x= 180°

=>15x=180°

=>x=180°/15

=>x= 12°

therefore the angles are:

4x=4*12=48°

5x=5*12=60°

6x=6*12=72°

Answer 2

let one angle = 4x

second angle = 5x

third angle = 6x

4x + 5x + 6x = 180º

15x = 180º

x = 180/15

x = 12º

first angle = 4x = 4*12 = 48º

second angle = 5x = 5*12 = 60º

third angle = 6x = 6*12 = 72º
