Question

the angles of a triangle are in the ratio 1:2:3.find the angles
​

Answer 1

Answer:

30°,60°,90°

Step-by-step explanation:

let angle be as X, 2x,3x

therefore, X+2x+3x =180. (angle sum property of∆)

6x = 180

X=30

2x = 60

3x= 90

if it would help you then follow me thanked me and report my answer as brainliest!!!!

Answer 2

Answer:

let the angels of triangle= x

• 1x + 2x + 3x = 180
• 6x = 180
• x = 180/6
• x = 30

1. 1x = 1 × 30 = 30
2. 2x = 2 × 30 = 60
3. 3x = 3 × 30 = 90

30,60,90
