Show that if the diagonal of a quadrilateral bisect each other at right angle,then it is a rhombus​

Answer»

Answer:-

Let ABCD be a quadrilateral whose diagonals bisect each other at right ANGLES.

GIVEN that:-

OA = OC

OB = OD

∠AOB = ∠BOC = ∠OCD = ∠ODA = 90°

To show that:-

If the diagonals of a quadrilateral bisect each other at right angles, then it is a rhombus.

To PROVE that:-

ABCD is parallelogram and AB = BC = CD = AD

Proof,

In ΔAOB and ΔCOB,

OA = OC (Given)

∠AOB = ∠COB (Opposite sides of a parallelogram are equal)

OB = OB (Common)

Therefore, ΔAOB ≅ ΔCOB [SAS congruency]

Thus, AB = BC [CPCT]

Similarly we can prove,

BC = CD

CD = AD

AD = AB

AB = BC = CD = AD

Opposites sides of a quadrilateral are equal hence ABCD is a parallelogram.

ABCD is rhombus as it is a parallelogram whose diagonals intersect at right angle.

Hence Proved.

Cosec square theta+ root 3 cot theta -7=0

Answer»

ANSWER:

we KNOW,

1 +  {<klux>COT</klux>}^{<klux>2</klux>} theta =  {cosec}^{2} \: theta

1 + cot^2 theta + √3 cot theta - 7=0

let cot theta = x

(x)^2 + √3x - 6 = 0

↪(x )^2 +2√3x - √3x - 6 = 0

↪x ( x + 2√3 ) - √3 ( x + 2√3 ) = 0

↪( x - √3 ) ( x + 2√3 )

↪ x = √3 OR x = -2√3

Therefor

cot theta = √3 OR cot theta = -2/√3

After receiving 3 successive discounts of 10%, 20% and 25% on MP of furniture, Maya purchased the furniture for rs. 9720. Determine the MP of the furniture.​

Answer»

ANSWER:

Price of furniture = 19285.71 Rs

Step-by-step explanation:

Let the price of furniture = x

The price after discount of 10% = x - 10% of x = x - x/10 = 9x / 10

The price after further discount of 20%  = 9x / 10 - 20% of 9x / 10

                                          = 9x / 10 - 18x/100 = 90x/100 - 18x / 100

                                                          = 72x / 100

The price after further 30% discount = 72x / 100 - 30% of 72x/100

                                                             = 720x/1000 - 3(72x)/1000                                                                    

                                                             =  720x/1000 - 216x/1000

                                                             = 504x/1000

According to given condition

                                      504x/1000 = 9720

                                                504x = 9720(1000)

                                                504x = 9720000

                                                       x = 9720000 / 504

                                                       x = 19,285.714285 Rs

Thus

Price of furniture = 19285.71 Rs
