Question

The angles of a triangle are in ratio 1:2:6. Find the angles . Give the solution

Answer 1

$x + 2x + 6x = 180 \\ 9x = 180 \\ x = 20 \\ 2x = 40 \\ 6x = 120$
where x 2x and 6x are the 3 angles

Answer 2

Angles of triange=1:2:6
let the angles be 1x,2x and 6x.
We know that the sum of interior angles of triangle is 180°
so, 1x+2x+6x=180°
9x=180°
x=180/9
x=20
So the value of x is 20.
Therefore first angle is 1*20=20°
second angle is 2*20=40°
and third angle is 6*20=120°
