Round your answer to two decimal places.

vaieri [72.5K]

Answer:

The correct answer is Hypotenuse = 3.61 units (Rounding to two decimal places)

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

Hypotenuse = 3.61 units (Rounding to two decimal places)
