Answer 1

Answer:

1. Commutative property of addition

i.e. a+b=b+a

2.let the angles be 2x,3x,4x

by ASP

2x+3x+4x=180

9x=180

x=20

angles are 40 degree, 60 degree, 80 degree

Answer 2

➡️✔ANSWER✔⬅️

THIS IS THE ✔COMMUTATIVE PROPERTY.✔

LET THE ANGLES BE 2x,3x and 4x.

Then,

2x+3x+4x=180°

(Angle sum property.)

=9x=180°

=x=180/9

=x=20°.

Therefore the angles are:

✔40°✔

✅60°✅

✔80°✔
