On a special right triangle if the sides are 6 and 6 then what is the hypothinus

Black_prince [1.1K]

We are talking about a right triangle so the phytagoras equation can be used:
$a^{2} + b^{2} = c^{2}$
$6^{2} + 6^{2} = 36 + 36 = 72 = c^{2}$
$\sqrt{ c^{2} } = \sqrt{72} =8.48528...$
So the hypothinus is equal to approximately 8.49
