Therefore, the final answer is: $oxed{answer}$. I hope it is correct.

Where [answer] is just the final number or expression that solves the problem.

Problem: An equilateral triangle $ABC$ shares a common side $BC$ with a square $BCDE,$ as pictured. What is the number of degrees in $\angle DAE$ (not pictured)? [asy]
pair pA, pB, pC, pD, pE;
pA = (0, 0);
pB = pA + dir(300);
pC = pA + dir(240);
pD = pC + dir(270);
pE = pB + dir(270);
draw(pA--pB--pC--pA);
draw(pB--pC--pD--pE--pB);
label("$A$", pA, N);
label("$B$", pB, E);
label("$C$", pC, W);
label("$D$", pD, SW);
label("$E$", pE, SE);
