We need to use the distance formula:
d = √( (x2-x1)² + (y2-y1)² )
The coordinates of each player are:
Arthur : (15,30)
Jamie : (40, 15)
Cameron: (55,45)
Distance between arthur and jamie:
d = √( (40-15)² + (15-30)²) = 29.1548 = 29
Distance between arthur and cameron:
d = √( (55-15)² + (45-30)² ) = 42.72 = 43
Distance beetween jamie and cameron:
d = √( (55-40)² + (45-15)² ) = 33.54 = 34
