Question

In the diagram below, O is circumscribed about quadrilateral DEFG. What is

Answer 1

Since O is circumscribed about quadrilateral DEFG, the value of x is equal to: D. 68°.

What is a supplementary angle?

A supplementary angle can be defined as two (2) angles or arc whose sum is always equal to 180 degrees. Mathematically, a supplementary angle can be calculated as follows:

Q + R = 180°.

In Geometry, the opposite angles of any cyclic quadrilateral that is inscribed inside a circle always form a supplementary angle. Thus, we would determine the value of x by using the mathematical expression above:

x + 112° = 180°

x = 180° - 112°

x = 68°
