The required proof of parallelogram is given below,

What is parallelogram?

A parallelogram is a straightforward quadrilateral with two sets of parallel sides in Euclidean geometry. The opposing or confronting sides and the opposing angles in a parallelogram are of equal length.

For a parallelogram, opposite sides are always equal and parallel.
So for the given parallelogram, we get AD = BC and AD and BC are parallel.

AD and BC is parallel and DC is common side, therefore, \angle 1 = \angle 3 ......(1)

Given \angle 3 = \angle 2  .......(2)

Therefore, from condition (1) and (2), we get

\angle 1 = \angle 2

If \angle 1 = \angle 2 then DC bisects the angle \angle ADE. [Proved]

Which quadratic rule represents the data in the table?
NeX [460]
Since there are already choices in the question, I suggest you just substitute in the values of x to each choice and check whether the corresponding value for y appears. This is also called the trial and error method in multiple choice.

The answer that represents the data in the table is C. <span>y = x^2 – 5.</span>

Sinxcosxtanx=1-cos^2x
ycow [4]

Step-by-step explanation:

sin  x \: cos  x \: tanx = 1 -  {cos}^{2} x \\ LHS \\= sin  x \: cos  x \: tanx \\  =sin  x \: cos  x \: \times  \frac{sin  x}{cos  x}  \\  = sin  x \: \times  \frac{sin  x}{1} \\  ={sin}^{2}  x \\  = 1 -  {cos}^{2} x \\  = RHS \\  \therefore \: sin  x \: cos  x \: tanx = 1 -  {cos}^{2} x \\ Hence \: Proved.
