Answer 1

RS ≈ 5.83 units

Explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

Here RS is the hypotenuse and the legs have measure 5 and 3, thus

RS² = 5² + 3² = 25 + 9 = 34 ( take the square root of both sides )

RS =
`√(34)` ≈ 5.83 ( to 3 significant figures )

Answer 2

5.831

Explanation:

Pythagoras says RS = √(5²+3²) = √34 ≈ 5.831
