Question

Find the angle of a triangle which are in ratio 1:3:6

Answer 1

Answer:

let the angles be 1x, 3x, 6x

WKT,

 1x + 3x + 6x = 180°  ( angle sum property )

  10x = 180°

  x = 180°/10

  x = 18°

Therefore, the angles are -- 1x = 1 x 18° = 18°

                                                3x = 3 x 18° = 54°

                                                6x = 6 x 18° = 108°

Hope it helps...

Answer 2

Let us consider the angles of the triangle to be,

x, 3x and 6x

x + 3x + 6x = 180°

(Sum of angles of a triangle= 180°)

10x = 180°

x = 18°

Therefore the angles are,

x = 18°

3x = 54°

6x = 108°
