Ilya [14]

Answer:

One example is the equation:

2x + 6 = 4x/2 + 12/2

To solve this, we need to transpose like terms to the same side.

2x - 4x/2 = 12/2 - 6

2x - 2x = 6 - 6

0 = 0

Since both sides are zero, it means that the equation has infinite number of solutions.

 If we have a basis of 2 units for the length of the side of the square,
then MV = NV = 1

Using pythagoeran theorem
MN = sqrt (MV^2 + NV^2)
MN = sqrt(2)

Therefore,
sin θ = 1 /√2
or
sin θ = √2 / 2
