Answer:

74°

Explanation:

Quadrilateral QUAD is inscribed in a circle. Therefore it is a cyclic quadrilateral. Opposite angles of a cyclic quadrilateral are supplementary.

$\therefore \angle D + \angle U = 180°\\\therefore \angle D + 106° = 180°\\\therefore \angle D = 180° - 106°\\\huge\purple {\boxed {\therefore \angle D = 74°}}$
