The values of x and y are not known and hence we cannot compare.
Hence D.

Hence B.

Hence B.

Hence B.

In the 30^{0}  60^{0}  90^{0} D ABC the side opposite 30^{0} ( i.e. AC ) is half the
hypotenuse AB i.e. AC = AB or AB = 2 AC.
Hence C.
In the right angled D ABC, AB^{2 } = BC^{2} + CA^{2} and CA = CD as D ACD is an isosceles triangle.
\ AB^{2} = BC^{2} + CD^{2}
Hence C.
In ( any ) D ABD, the sum of the lengths of any two sides is greater than the third side. Hence AB + AD > BD and BD = BC + CD.
Hence A.
