the 2nd expression is the answer
You do 250 divided by 9 and get 27.7777777777 you round that to 27.8 which is your answer
In order to find the lenght of the triangles you may use the next formula
<span>A(x1 , y1) , B(x2 , y2) </span>
<span>AB = sqrt[(x1-x2)^2+(y1-y2)^2]
</span>Still I have to say that the triangle you are describing is definitely Isosceles
I hope this works for you
