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

   Hence D.

2. 

   Hence B.

3. 

   Hence B.

4. 

   Hence B.

5. In the 30⁰ - 60⁰ - 90⁰ D ABC the side opposite 30⁰ ( i.e. AC ) is half the hypotenuse AB
   i.e. AC = AB or AB = 2 AC.

   Hence C.

6. In the right angled D ABC, AB² = BC² + CA² and CA = CD as D ACD is an isosceles triangle.
   \ AB² = BC² + CD²

   Hence C.

7. 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.
