The diagonal of a square is 4 cm . Find it's area.

Answer»

\:

Answer:

It is given that diagonal BD= 4 cm(See the enclosed figure)

Let each side of the square be 'a'.

Here, ∆BAD and ∆BCD are right TRIANGLES (ABCD is a square).

Now, applying PYTHAGORAS theorem in ∆ABD,

(Hypotenuse)²= (Base)²+(PERPENDICULAR

(BD)²= (AB)²+(AD)²

(4)²= (a)²+(a)²--------(All the sides of a square are EQUAL )

16= 2a²

16÷2= a²

8= a²

2√2 cm= a

Thus, each side of the square is of length 2√2 cm

Now, Area of a square= a² where a is the side

=> (2√2)²

=> 4×2

=> 8 cm²

Answer=> 8 cm²

7.

If ab is equal to 5 and a minus b is equal to 2 then find the value of a cube minus b cube​

Answer»

ANSWER:

Step-by-step explanation:

AB=5

a-b=2

then cubing both sides in a-b=2. We get

(a-b)^3=2^3

a^3-b^3-3ab(a-b)=8

Putting VALUES of ab and a-b we get

a^3-b^3-3×5(2)=8

a^3-b^3-30=8

a^3-b^3=8+30=30

a^3-b^3=38

prove that cos secant theta minus sin theta into secant theta minus cos theta equal to one by tan theta + cot theta​

Answer»

Step-by-step explanation:

To prove,

(COSEC θ - sin θ)(SEC θ - COS θ)(tan θ + cot θ)=1

Proof:

LHS =(1/sin θ - sin θ)(1/cos θ - cos θ)(tan θ+1/tan θ)

        =(1-sin²θ)/sinθ (1-cos²θ)/cosθ(1+tan²θ)/tanθ

        =(cos²θ)/sinθ (sin²θ)/cosθ sec²θ/tanθ

        =cos θ sin θ (1/cos²θ)/(sinθ/cosθ)

        =cos θ sin θ(1/cos²θ)(cosθ/sinθ)

        =cos θ sin θ (cos θ/sin θ cos²θ)

        =cos θ sin θ (1/sin θ cos θ)

        =cos θ sin θ/sin θ cos θ

        =1=RHS

           ∴ HENCE proved

EXERCISE 61. What would you subtract from 78,580 so that the difference is equal to the sum of24,682 and 13,579?​

Answer»

ANSWER:

Let the NUMBER = x

According to the QUESTION ,

78580 - x = 24682 + 13579

78580 - x = 38261

78580 - 38361 = x

= > x = 78580 - 38361

x = 40319.

Therefore ,

x = 40319.

The points (-2,5) and (3,-5) are plotted in xy planes. Find the slope and y intercept of the line joining the points.​

Answer»

ANSWER:

Step-by-step explanation:

As the points given as(-2,5) and (3,-5).

Now, slope(m) has the formulae as

m=(y2-y1)/(x2-x1).

Now, here x1 and y1 are -2 and 5.

And x2 and y2 is 3 and -5.

Hence,

Slope m=(-5-5)/(3-(-2))

m=-10/5 = -2

Now, putting the VALUE of m in the equation of a straight line

y=mx +C

y= -2x +c

Putting the value of any point in the equation

LET (-2,5).

5=-2*-2+c

c= 5-4= 1

Hence, y INTERCEPT is 1.

If you would have taken the value of (3,-5) same value of c which is y intercept would have come.

45.

If two consecutive odd number whosesum is 1242)if two supplementary angles differ by 36, find them​

Answer»

Answer:

Step-by-step explanation:

1)let the TWO consecutive no.s be x and x+2

x+x+2=124

2x =124-2=122

x=122/2

61

so the consecutive odd no.s are 61 and 61+2=63

2)

let the two SUPPLEMENTARY ANGLES be x and y.

according to the question - x-y =36, x+y=180

x+y=180

x-y=36

2x=216

x=216/2=108

as x+y =180

y=180-108=72

x=108,y=72.

Find the x-intercept and the y-intercept for 2x+y=8 then use them to graph the line.

Answer»

Find the x-intercept by SUBSTITUTING in 0 for y and solving for x.

Find the y-intercept by substituting in 0 for x and solving for y.

Let's find the x-intercept FIRST: 2x + (0) = 8

2x = 8

Divide both sides by 2 to isolate and solve for the variable "x", or the x-intercept.

x = 4 (x-intercept)

Now find the y-intercept: 2(0) + y = 8  

Multiply 2 and 0.

y = 8 (y-intercept)

You have found the x-intercept to be 4 and the y-intercept to be 8. To graph the LINE, place a point on (4, 0) ← x-intercept and a point on (0, 8) ← y-intercept.

Your line should look like the attached image :)

SUM of 24682 and 13570 = 38252

Let the NUMBER be x .           (Which is to be SUBTRACTED)

According to QUESTION,

17580 - x = 38252

=> x = 38252 - 17580 = 20672
