Question

The three angles of a triangle are in the ratio 1: 2: 3, then the greatest angle is​

Answer 1

Answer:

sum of the angles of a triangle is 180

ratio=1:2:3

sum of ratio is 6

=180/6

=30

=the angles are

=30×1

=30×2

=30×3

=30,60,90

the largest angle is 90

the answer is 90 degrees

please mark as brainliest answer if helpful

Answer 2

Answer:

Let the ratio of angle be x.

by angle sum property,

1x+2x+3x=180

6x=180

x=30

The angles are 30,60 and 90.

therefore, the greatest angle is 90.
