Three vertices of a square are A(-1, -9), B(3, -1) and C(-5, 3). Plot the points. Then find the coordinates of the missing vertex D​

Answer»

ong>Given :- Three vertices of a square are A(-1, -9), B(3, -1) and C(-5, 3) .

To Find :- find the coordinates of the missing vertex D ?

Concept and formula used :-

  • Diagonals of a square are equal in length and bisect each other.
  • Mid - Point formula :- if (x,y) is EQUIDISTANT from (X1,y1) and (x2,Y2) than, x = (x1 + x2)/2 and y = (y1 + y2)/2 .

Solution :-

Given that, A(-1, -9), B(3, -1) and C(-5, 3) .

Let coordinates of D are (x,y).

So,

we told above in square , diagonals are same and bisect each other.

Using mid - point formula we get,

→ mid point of AC = mid point of BD

Putting values we get,

→ {(-1 - 5)/2 , (-9 + 3)/2} = {(3 + x)/2 , (-1 + y)/2}

→ (-3, -3) = {(3 + x)/2 , (-1 + y)/2}

Comparing both we get,

→ (3 + x)/2 = (-3)

→ 3 + x = 2 * (-3)

→ 3 + x = (-6)

→ x = (-6) - 3

→ x = (-9) .

and,

→ (-1 + y)/ 2 = (-3)

→ (-1 + y) = 2 * (-3)

→ y - 1 = (-6)

→ y = (-6) + 1

→ y = (-5)

Hence, coordinates of the missing vertex D are {(-9) , (-5)}.

When the axes are rotated through an angle 30° find the new coordinates of the (0,0)​

Answer»

ong>ANSWER:

x' = x COS(θ) + y SIN(θ)

y' = - x sin(θ) + y cos(θ)

So,

x' = -2(√3/2) + 4(1/2) = 2 - √3

y' = 2(1/2) + (4)(√3/2) = 1 + 2√3

New coordinates = (2 - √3, 1 + 2√3)

Solve Don't tell me if you can't answer it and don't spam Thank you.

Answer»

ong>Answer:

\sqrt{<klux>X</klux>  + 3}  = x + 1

by squaring on both sides,

{ (\sqrt{x + 3} )}^{2}  = (x + 1) ^{2}  \\ x + 3 =  {x}^{2}  +  {1}^{2}  + 2(x)(1)

[{a}^{2}  +  {b}^{2}  + 2ab = (a + b) ^{2}]

x + 3 =  {x}^{2}  + 1 + 2x \\  {x}^{2}  + 2x + 1 = x + 3 \\  {x}^{2} + 2x - x + 1 - 3 = 0 \\  {x}^{2}  + 2x - x  - 2 = 0

Here we didn't subtract 2x-x because if we do FACTORIZATION again we will GET the same EQUATION.

x(x + 2)  - 1(x + 2) = 0 \\ (x - 1)(x + 2) = 0 \\ here \: (x - 1) = 0 \: (or) \: (x + 2) = 0 \\ x  - 1 = 0 \: (or) \: x + 2 = 0 \\ x =   1 \: (or) \: x = ( - 2)

The VALUE of x is 1 or (-2).

I hope it is helpful.

the area of a square field is 5625m√ . A rectangular field whose length is twice its breadth an has its perimeter equal to the perimeter of the square field. Find the dimensions of the rectangle​........​

Answer» ONG>

Given :-

The area of a square field is 5625m² . A rectangular field whose length is TWICE its breadth an has its perimeter equal to the perimeter of the square field

To find :-

Dimensions of rectangle

Solution :-

Area of square = 5625 m²

→ side × side = 5625

→ a² = 5625

→ a = √5625

→ a = 75M

Perimeter of square

→ 4 × side

→ 4 × 75

→ 300m ---(i)

Now,

Let the breadth be x then length be 2X of rectangle

As per given condition

Perimeter of rectangle = Perimeter of square

→ 2(l + b) = 4 × side

→ 2(2x + x) = 300 (Using i)

→ 2 × 3x = 300

→ 6x = 300

→ x = 300/6

→ x = 50 m

HENCE,

Breadth of rectangle = x = 50m

Length of rectangle = 2x = 100m
