In the below figure, $EB$ is tangent to the circle with center $C$ at the point $B$. If $EC$ is equal to the diameter of the circle, find the measure of angle $BAD$ in degrees.

pair C = (0,0), B = dir(110), D = dir(170), E2 = 2 * D, A = dir (305);
draw(unitcircle);
draw(C--E2--B--C^^D--A--B);
dot(A^^B^^C^^D^^E2);
label("$A$",A,SE);
label("$B$",B,NW);
label("$C$",C,S);
label("$D$",D,SW);
label("$E$",E2,W);
