The diagonals AC

Answer :

Given,


ABCD is a rectangle



Diagonals AC & BD intersect each other at P


ABD = 50°


diagonals of rectangle bisect each other and are equal in length


=ABD= PDC [alternate angles]


PDC=PCD = 50°


In ∆DPC


=DPC+PCD+PDC = 180°


= DPC+50°+50°= 180°


= DPC = 180°-100° = 80°
