Answer 1

Ratio of angles of triangle = 1:2:3

Let the common multiple be x

1st angle = 1x

2nd angle = 2x

3rd angle = 3x

According to angle sun property of a triangle,

x+2x+3x = 180⁰

=> 6x = 180⁰

=> x = 180⁰/6

=> x = 30⁰

1st angle = x = 30⁰

2nd angle = 2x = 2×30⁰ = 60⁰

3rd angle = 3x = 3×30⁰ = 90⁰

Hope it helps...

Answer 2

Step-by-step explanation:

let the ratios be 'x'

<1=1x,<2=2x and <3=3x

<1+<2+<3=180(angle sum property)

1x+2x+3x=180

6x=180

x=180/6

x=30

<1=30

<2=60

<3=90
