Answer 2

135°

Explanation:

WILD is a cyclic quadrilateral.

Opposite angles in a cyclic quadrilateral are Supplementary.

`\therefore \angle \: I + \angle \: D = 180 \degree \\ \\ \therefore 45 \degree + \angle \: D = 180 \degree \\ \\ \therefore 45 \degree + \angle \: D = 180 \degree \\ \\ \therefore\angle \: D = 180 \degree - 45 \degree \\ \\ \huge \red{ \boxed{\therefore\angle \: D = 135 \degree }}`
