The circle theoremss that cyclic quadrilaterals can be related to include:
- Every corner of the quadrilateral touches the circumference of the circle.
- The ratio between the diagonals and the sides can be defined.
- The product of the diagonals is equal to the sum of the product of its two pairs of opposite sides.
<h3>What is a cyclic quadrilateral?</h3>
It should be noted that cyclic quadrilateral simply means a quadrilateral that's drawn inside a circle.
In this case, every corner of the quadrilateral must touch the circumference of the circle.
Also, the product of the diagonals is equal to the sum of the product of its two pairs of opposite sides.

Angle 1, 4, and 8 are all congruent to angle 5. The last choice would be correct.
Answer:
(x - 2) or (x + 5)
Step-by-step explanation:
Step 1: Write quadratic
x² + 3x - 10
Step 2: Factor
(x - 2)(x + 5)
Answer:
x = 20
y = 8
In a parallelogram, there are always two pairs of equal sides, where in this question:
Side CD = Side BA
Side DA = Side CB
Use this to find x and y.
CD = BA
15 = x - 5
x = 20 (rearranging to find x)
DA = CB
y = 8
