Question

if one angle of a triangle is 60° and the other two angles are in ratio 1:2 find the angle​

Answer 1

Step-by-step explanation:

Let the angles be x and 2x.

So,

60+ x+2x= 180°. { Angle Sum Property}

3x= 120°

x= 40°

2x= 80°

Answer 2

Answer:

One angle of a triangle =60

∘

Other two angles are in the ratio 2:3

Sum of other two angles =180

∘

−60

∘

=120

∘

Let one of other two angles =2x

Then third angle =3x

2x+3x=120

∘

5x=120

∘

x=24

Other two angles are 2x=2×24=48

∘

and 3x=3×24=72

∘

Other two angles of the triangle are 48

∘

,72
