Question

If the angles of a triangle are in ratio 1 : 2 : 3 determine three angles

Answer 1

Answer:

let the angles be x,2x,3x.

We know that sum of all the angles of a triangle is 180°.

So,x+2x+3x=180°

6x=180°

x=30°

Hence,the angles are30°,60°,90°.

Answer 2

Answer:

let's the angle 1 to 1x and 2x and3x.

so the total length of triangle is 180degree.

now 1x+2x+3x = 180°

6x= 180°

x=180°
