PLZ HELP ASAP INSCRIBED QUADRILATERIALS

1 answer:

7 0

For quadrilaterals inscribed in a circle, the opposite angles must sum up to 180 degrees. Therefore, angle I + angle D should add up to 180
45 + angle D = 180
angle D = 135 degrees.

(Similarly, angles L & W would also add up to 180, and angle L = 81 degrees.)

Answer: 90 textbooks

Step-by-step explanation:
