Answer:
the forth
Step-by-step explanation:
you know that hipotenusa is the longest side in a rectangle triangle and its formula is H=[tex]\sqrt{l1^2+l2^2}[/tex]
for each group of number you apply the formula you will see that 13 and 84 do not have 85 as hipotenusa
Answer:
13, 84, 86
Step-by-step explanation:
Using Pythagorean's Theorem, a^2 + b^2 = c^2, where a and b are two legs and c is the hypotenuse.
6^2 + 8^2 = 10^2.
30^2 + 40^2 = 50^2
25^2 + 60^2 = 65^2
All of these expressions are true, but
13^2 + 84^ ≠ 86^2
Therefore, 13, 84, and 86 cannot be the three sides of a right triangle.
