Round your answer to two decimal places.

Answer:

<u>The correct answer is Hypotenuse =  3.61 units (Rounding to two decimal places)</u>

Step-by-step explanation:

We can use the Pythagoras theorem formula for solving this questions. It can be expressed symbolically as follows:  

Hypotenuse² = First leg² + Second leg²

 "The amount of units comprising the hypotenuse squared is equal to the addition of the measure of both legs squared."

Hypotenuse² = First leg² + Second leg²

Hypotenuse =  √(First leg² + Second leg² )

Replacing with the real values:

Hypotenuse =  √(3² + 2² )

Hypotenuse =  √(9 + 4 )

Hypotenuse =  √13

Hypotenuse =  3.60555

<u>Hypotenuse =  3.61 units (Rounding to two decimal places)</u>
