Question

The three angles of abc are in the ratio 1:2:1.Find all the angles of the triangle

Answer 1

Answer:

let the ratio of the angle be x , 2x and x

now,

sum of all angles = 180°

=> x + 2x + x = 180

=> 4x = 180

=> x = 45°

so, the angles are , x = 45°

2x = 90°

and third angles, x = 45°

Answer 2

Answer:

Hey mate here is your answer.

Step-by-step explanation:

a:b:c=1:2:1,

So we should find all angles,

As,sum of all angles∠a+∠b+∠c=180°.

1+2+1=4,

so,∠a:1/4×1

80,

= 45°.

∠b:1/2×180,

=90°.

∠c:1/4×180,

=45°.

so,the angles of the triangles are:45°,90°,45°.
