Well half of 500 is 250 so one person gets 300$ and the other gets 250$
Answer:
![m\angle ECB+m\angle EFB=180](https://tex.z-dn.net/?f=m%5Cangle%20ECB%2Bm%5Cangle%20EFB%3D180)
![m\angle CDB\cong m\angle EDF](https://tex.z-dn.net/?f=m%5Cangle%20CDB%5Ccong%20m%5Cangle%20EDF)
![m\angle CDB+m\angle DCB+m\angle CBD=180 \degree](https://tex.z-dn.net/?f=m%5Cangle%20CDB%2Bm%5Cangle%20DCB%2Bm%5Cangle%20CBD%3D180%20%5Cdegree)
Step-by-step explanation:
From the diagram, quadrilateral BCEF is a cyclic quadrilateral.
Opposite angles if a cyclic quadrilateral sum up to 180°
![m\angle ECB+m\angle EFB=180](https://tex.z-dn.net/?f=m%5Cangle%20ECB%2Bm%5Cangle%20EFB%3D180)
The diagonals intersect at D to form two pairs of vertical angles, and vertical angles are congruent.
![m\angle CDB\cong m\angle EDF](https://tex.z-dn.net/?f=m%5Cangle%20CDB%5Ccong%20m%5Cangle%20EDF)
Also sum of angles in triangle CBD is 180°.
![m\angle CDB+m\angle DCB+m\angle CBD=180 \degree](https://tex.z-dn.net/?f=m%5Cangle%20CDB%2Bm%5Cangle%20DCB%2Bm%5Cangle%20CBD%3D180%20%5Cdegree)
