Question

What is the length of BC​

Answer 1

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
