Question

the angle of a triangle are in the ratio 1 : 2 : 6. find the angle

Answer 1

hey there!! here is ur answer....
Let the angles are x, 2x, 6x

Now we know the sum of all angles of a triangle is 180•

so,
x+2x+6x=180
9x=180
x=180/9
x=20

then, the angles are:-
1x=20
2x=40. and
6x=120

hope it helps u :)

Answer 2

Let the ratio be x.
→x,2x,6x.
We know that:
✓A+✓B+✓C=180°.

A/Q
x+2x+6x=180°.
→9x=180°.
→x=180°/9
→x=20°.

✓A=x=20°.
✓B=2x=2×20°=40°.
✓C=6x=6×20°=120°.
