10,10 and 20 cannot as 10+10=20 so there would be a triangle with no area.
The others can all be the sides of a triangle as 7+7>8, 7+6>11 and 2+8>9.
Answer:
![\sqrt{85}](https://tex.z-dn.net/?f=%5Csqrt%7B85%7D)
Step-by-step explanation:
To calculate the distance (d) use the distance formula
d = √ (x₂ - x₁ )² + ( y₂ - y₁ )²
with (x₁, y₁ ) = (- 1, 4) and (x₂, y₂ ) = (6, - 2)
d = ![\sqrt{(6+1)^2+(-2-4)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%286%2B1%29%5E2%2B%28-2-4%29%5E2%7D)
= ![\sqrt{7^2+(-6)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B7%5E2%2B%28-6%29%5E2%7D)
=
=
← exact distance
I don't know how it was discovered, but i do know for a fact that it is 22 divided by 7
