Question from Joie, a student:

Quadrilateral ABCD is inscribed in a circle such that side DA is the diameter. AB=2m., BC=4m., CD=6m., angle BAD=75.93degrees. Find the area of the quadrilateral.

Hi Joie,

The key to this problem is that the opposite angles in any quadrilateral inscribed in a circle are supplements of each other.

Do you see now how to solve this problem?
