Question

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

Square root of 18 units
Square root of 27 units
3 units
6 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 = √(18)`

Therefore the answer is Square root of 18 units.

Hope it helps!
