Question

What is the length of the missing leg if necessary round to the nearest tenth

Answer 1

Answer:

the second answer : 4.5

Step-by-step explanation:

remember Pythagoras :

c² = a² + b²

c being the Hypotenuse (the baseline opposite of the 90° angle).

so, we have

6² = 4² + b²

36 = 16 + b²

b² = 20

b = sqrt(20) = 4.472135955... ≈ 4.5 mm
