Question

What is the length, in units, of the hypotenuse of a right triangle if each of the two legs is 3 units?

Answer 1

A: Square root of 18 units

Answer 2

To find the hypotenuse,we can use the Pythagoras Theorem:
${c}^{2} = {a}^{2} + {b}^{2}$
Where c is the hypotenuse and a,b are the legs.

In this case:
${c}^{2} = {3}^{2} + {3}^{2} \\ {c}^{2} = 9 + 9 \\ {c}^{2} = 18 \\ c = \sqrt{18}$

Therefore the answer is Square root of 18 units.

Hope it helps!
