Answer 1

hope its help u___,,,,,,,

Answer 2

Step-by-step explanation:

let the first angle be x

so, the other angle will be 2×x

the third angle,

= x+2x

=3x

their degree measures are

x+2x+3x=180°

6x=180°

x=180/6

x=30°

first angle = x = 30°

second angle =2x = 2×30

=60°

third angle =3x =3×30

=90°
