the angle of triangle are in the ratio 1: 2: 6. find the angle. hint: sum of angle of a triangle=180
MohdUvais:
20degree,40degree, 120degree
LET THE ANGLES BE x,2x,6x respectively.
=> x+2x+6x= 180. => 9x=180. => x=20
Therefore, the angles are,. 2
20,40,120
Correct
answer is 30 60 and 90

SALUT AMIS !!
Ratio = 1 :2: 6:
Let the angles be = 1x,2x,,6x
Then 1x+2x+6x = 180 [Angle Sum Property of a triangle]
3x + 6x = 180
9x = 180
x = 180/9
x = 20
Therefore the angles are :
1x = 20 × 1 = 20
2x = 20× 2 = 40
6x = 20 × 6 = 120
Verification = 20 + 40 + 120 = 180
Hope it helps ...!!

let the ratio =X
X=1x,Y=2x,Z=6x,
sum of all angles of triangle=180°
1x+2x+6x=180°
9x=180°
X=180/9
X=20°
so,angle X =20°. Y=2*20=40°. Z= 6*20=120°
X=1x,Y=2x,Z=6x,
sum of all angles of triangle=180°
1x+2x+6x=180°
9x=180°
X=180/9
X=20°
so,angle X =20°. Y=2*20=40°. Z= 6*20=120°
