In the diagram, point D divides line segment AB in the ratio of 5:3. If line segment AC is vertical and line segment CD is horizontal, what are the coordinates of point C?

Angle  (CAD) = 45º          Ratio  AD :  BD  is   5 : 3

 

AB = 8 / sin(45º) = 8√2         AD = 5√2           BD = 3√2

 

AC = CD = sin(45º) * 5√2  

 

C = (2,-1)
