Question

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

Answer 1

let the three angles are 1x,2x,3x,
sum of angles=180 degree
1x+2x+3x=180
6x= 180
x= 30
then angles are30,60,90
so triangle is Right Angle Triangle

Answer 2

Let the angle be,
x y, z
Therefore, x:y:z=1:2:3
X=k
Y=2k
Z=3k

By angle sum property of triangle
x+y+z = 180°
K+2k+3k=180°
6k=180°
K=180/6
K=30

Therefore, x=k=30°
y=2k=2(30)=60°
z=3k=3(30)=90°
