The angle of a triangle is 3:1:2.the measure of the largest angle is?

1.	The angle of a triangle is 3:1:2.the measure of the largest angle is? I cannot understand how to get 180from West Bengal
Answer» 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 = 330 = 90° x = 30° 2x = 230 = 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 :)

Answer:

Let the angles of TRIANGLE be

1x = x

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°
