Let \(ABC\) be a triangle with \(AB = AC\). The angle bisectors of \(∠CAB\) and \(∠ABC\)
meet the sides \(BC\) and \(CA\) at \(D\) and \(E\), respectively. Let \(K\) be the incenter of
triangle \(ADC\) . Suppose that \(∠BEK = 45 ^\circ\) Find all possible values of \(∠CAB\), and take their average.
