Question

Can you please help me before I get on error message and get kicked out

Answer 1

We have the following:

What we must do is calculate the total rate, that is, add all of them and then calculate each part, that is:

`4+5+5+8+9+9=40`

Now we calculate each angle like this

`\begin{gathered} 720\cdot(4)/(40)=72 \\ 720\cdot(5)/(40)=90 \\ 720\cdot(8)/(40)=144 \\ 720\cdot(9)/(40)=162 \\ we\text{ add} \\ 72+90+90+144+162+162=720 \end{gathered}`

then we can affirm that the smallest angle is 72 °
