Since the quadrilateral is inscribed inside the circle, where the four vertices are on the circle itself, this means that the opposite angles add to 180 degrees.

Angle I and Angle D are opposite angles. They add to 180 degrees

(angle I) + (angle D) = 180
(45 degrees) + (angle D) = 180
(angle D) + 45 = 180
(angle D) + 45 - 45 = 180 - 45 ... subtract 45 from both sides
angle D = 135

The measure of angle D is 135 degrees

Thye given Quadrilateral WILD is inscribed in circle O. The measure of angle D is 135 degrees.

Since the quadrilateral is inscribed inside the circle,

Where the four vertices are on the circle itself,

What is the addition opposite angle?

The opposite angle addition is 180 degrees.

Angle I and Angle D are opposite angles.

They add to 180 degrees

(angle I) + (angle D) = 180

(45 degrees) + (angle D) = 180

(angle D) + 45 = 180

(angle D) + 45 - 45 = 180 - 45 ... subtract 45 from both sides.

angle D = 135

The measure of angle D is 135 degrees.
