Answer:

Step-by-step explanation:
To find the length of an isosceles triangle, you know that the angles of the triangle are 45-45-90, so let's use that triangle theorem.
Therefore, the length of the hypotenuse (BD) is
, and x is equal to 8 (length of BC).

x=8
Therefore,
would be the length of side BD.
