$A B = 20$ $AB=20$

Explanation:

$¯ ¯¯¯¯ ¯ D B$ $bar(DB)$ is a median to $¯ ¯¯¯¯ ¯ A C$ $bar(AC)$ , therefore by definition $B$ $B$ is the midpoint of $¯ ¯¯¯¯ ¯ A C$ $bar(AC)$ . Since $B$ $B$ is the midpoint of $¯ ¯¯¯¯ ¯ A C$ $bar(AC)$ , $¯ ¯¯¯¯ ¯ A B ≅ ¯ ¯¯¯¯ ¯ B C$ $bar(AB)congbar(BC)$ , therefore $A B = B C$ $AB=BC$ . Since $B C = 20$ $BC=20$ and $A B = B C$ $AB=BC$ , $A B = 20$ $AB=20$ .
