Question

Two consecutive angles of a parallelogram are (x + 60)° and (2x + 30)°.

What special name can you give to this parallelogram ?​

Answer 1

Answer:

x will equal to 30 degree because sum of two consecutive angle of parallelogram is 180

Answer 2

Answer:

In order to prove this ,

Let us use the formula :

x3 + y3 + z3 - 3xyz = ( x + y + z) (x2 + y2 + z2 - xy - yz - xz)

Now let us keep x + y + z = 0

So,

x3 + y3 + z3 - 3xyz = 0

x3 + y3 + z3 = 3xyz
