Are you serious @hba ??

hba · Answer

I used the formula,

Share=indivual ratio*total/sum
         =3*180/6=90


Right ?

Tell me right or wrong ?

anonymous · Answer

Right...

hba · Answer

Yeah thanks lol :P

anonymous · Answer

Moreover you can do like this :

As you are given with ratio so :

Let the angles be : x, 3x and 2x..

Three angles are supplementary, so

x + 3x + 2x = 180

Here : x = 30..

So : Angle(b) = 3x = 3*30 = 90 degrees..
