Answer Key : (a,c) -

(a,c)

It is clear that diagonals of the rhombus will be parallel to the bisectors of the given lines and will pass through (1, 3). Equations of bisectors of the given lines are

or

Therefore, the equations of diagonals are and . Thus the required vertex will be the point where these lines meet the line . Solving these lines we get possible coordinates as (8/5, 16/5) and (6/5, 12/5)
