Answer:
BC = 2
Step-by-step explanation:
We first need to use triangle BAD to find BD,
BD is the hypotenuse, so use pythagorean theorem...
(√23)² + (√13)² = (BD)²
23 + 13 = (BD)²
36 = (BD)²
6 = BD
Now BD is the hypotenuse of triangle BCD, so use pythagorean theorem agian to find BC
(4√2)² + (BC)² = 6²
32 + (BC)² = 36
(BC)² = 4
BC = 2
(0,-9) or (1,-7) or (2,-5) either one would be correct
No Alana's mom cannot be 3 times her age because 8 multiplied by 3 equals 24, Alana's mom would have to be 4 times her age. (8 multiplied by 4 equals 32)
