Answer:
RS ≈ 5.83 units
Step-by-step 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 = [tex]\sqrt{34}[/tex] ≈ 5.83 ( to 3 significant figures )
