Answer:
BC ≈ 8.6
Step-by-step explanation:
Using Pythagoras' identity in the right triangle , that is
BC² = AB² + AC² = 7.3² + 4.6² = 53.29 + 21.16 = 74.45 ( square root both sides )
BC =
≈ 8.6 ( to 1 dec. place )

Answer: 18</h3>
We multiply the length of AB by 2 to get the length of A'B'
9*2 = 18
If you’re looking for the probability it’s 1/10
