Question

the angles of a triangle are in the ratio 1:2:3.the measure of the largest 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

Answer 2

Answer:

Angles of triangles are 30°, 60° and 90 ° respectively.

Then , the largest angle of triangle is 90°.

Step-by-step explanation:

Let the angles of triangle be x, 2x, and 3x respextively.

According to the question

Sum of angles of triangle = 180°

x + 2x + 3x = 180°

6x = 180°

x = 180°/6

x = 30°

2x = 2 × 30° = 60°

3x = 3 × 30° = 90°

Then,

Angles of triangles are 30°, 60° and 90 ° respectively.

Then ,

The largest angle of triangle is 90°
