Question

The angle of a triangle are in the ratio 3:1:2.Find the angles and classify the triangle.​

Answer 1

Answer:

90, 30, 60

Step-by-step explanation:

3:1:2

take it as 3x:1x:2x

3x+1x+2x=180 deg (By Angle sum Property)

6x=180

x=180/6

x=30

3x=3(30)=90

1x=1(30)=30

2x=2(30)=60

Answer 2

Answer :-

Let the angles of a triangle be 3x, x, 2x.

According to question :-

=> 3x + x + 2x = 180° (sum of angles of a triangle is 180°)

=> 6x = 180°

=> x = 180/6

=> x = 30°

So, the angles of a triangle are :-

★ 3x = 3 (30) = 90°

★ x = 30

★ 2x = 2 (30) = 60°

Angles of triangle are 90°, 30°, 60°.

This triangle is Right-angled triangle.
