It looks alright to me but i would check it again see if you missed anything <span />
Step-by-step explanation:
we need much more information. you don't show us the diagram of the shape. for example.
it is impossible to know what you mean by a general angle between 3 points (?).
and we cannot even see the full screen shot.
Just plug in 3 for x
y = -( 2^3 )
y = -( 8 )
y = -8
6 because 14 divided by 2 is 7 and hassan would be the 7th one.
The square root of 110 is 10.48 rounded off is 10.5
