Answer:
No
Step-by-step explanation:
By using the Pythagoras theorem, it can be easily determined that whether the triangle is right triangle or not.
Thus, [tex]a^{2}+b^{2}=c^{2}[/tex] where where a and b are the legs and c is the hypotenuse.
Let a=6ft, b=21ft and c=23ft, then
[tex]a^{2}+b^{2}=c^{2}[/tex]
[tex](6)^{2}+(21)^{2}=(23)^{2}[/tex]
[tex]36+441=(23)^{2}[/tex]
[tex]477=529[/tex]
which is not possible, therefore the given triangle is not right triangle because it does not satisfy the Pythagoras theorem.
