Question

the angle of a triangle is 3:1:2.the measure of the largest angle is? I cannot understand how to get 180



from West Bengal​

Answer 1

Answer:

Let the angles of triangle be

3x

1x = x

2x

Now, by angle sum property of a triangle

3x + x + 2x = 180°

6x = 180°

x = 180°/6

x = 30°

now,

3x = 3*30 = 90°

x = 30°

2x = 2*30 = 60°

So, the largest angle of the triangle is 90°.

I cannot understand how to get 180°. (your question)

Angle sum property of a triangle says that the sum of all it's interior angle is 180°

Hope it helps u
