Explanation:

♤You can solve using the pythagorean theorem.

♡We will be using the variable 'x' to represent the variable 'b' in the picture provided.

◇In the pythagorean theorem, a and b represents bases while the c represents the hypotenuse (diagonal).

`{a}^(2) + {b}^(2) = {c}^(2) \\ {x}^(2) + {12}^(2) = {20}^(2) \\ {x}^(2) + 144 = 400 \\ \frac{ \: \: \: \: \: - 144 = - 144}{ {x}^(2) = √(256) } \\ x = 16`
