Question

if the angles abc of triangle abc are in ratio of 1:2:3 what sort of triangle is this

Answer 1

sum of three angles of a triangle is 184 One X + 2 X + 3 x is equal to 180 therefore 6 x is equal to 180 degrees therefore x is equal to 30°therefore this Triangle is scalene Triangle

Answer 2

Answer:

Let the angles of a triangleA ,B and C = x , 2x and

3x

We know that ,

The sum of all angles of a triangle = 180°

x + 2x + 3x = 180 °

6x = 180°

X = 180°/6

X = 30°

Hence , the angles of a triangle =

A= 30° , B= 2x30° = 60°

, C = 3X30° = 90°

Here , one angle of triangle is 90°So, this triangle is Right-Angled triangle
