Question

if the angle of a triangle are in the ratio 1:2:3 determine its angle​

Answer 1

Step-by-step explanation:

Let the angles be 1x,2x,3x.

Using theorem, Sum of interior angles of a triangle is 180o .

We get ∠A+∠B+∠C=180o 

⇒1x+2x+3x=180o

⇒6x=180o

⇒x=30o

∴ Angles are 30o,60o,90o.

Answer 2

Answer:

1 x+2x+3x =180

6x=180

×=30

Step-by-step explanation:

angles are 30 60 90
