Question

Angles of y, 2y, 3y, 6y and 8y, form one revolution. Calculate the smallest angle please.​

Answer 1

If you mean that they form one revolution when summed up together, then we have

`y+2y+3y+6y+8y=(1+2+3+6+8)y=20y`

One revolution is 360 degrees, so we have

`20y=360 \iff y=(360)/(20)=18`
