Step-by-step explanation:

World heritage sites are RECOGNIZED by UNESCO. The countries have to make a case with UNESCO and the organization will evaluate and decide the same for cultural, historic, SCIENTIFIC or other FORMS of significance.

Italy has 51 sites, followed by China with 50 sites. SPAIN has 45, France 42, GERMANY 41, India 35 and Mexico 34. Perhaps it is because how well the respective countries projects their heritage sites with UNESCO.

Happy to Help

ong>ANSWER:

Here is the solution .

Hope it HELPS.

=) =)

eems that the QUESTION has a flaw

instead of

sin a + COS a = 2

it should be

sin a + cosec a = 2

I am proceeding to solve taking this as correct

sin a + cosec a = 2

SQUARING both side

(sin a + cosec a )^2 = 2^2

sin^2 a + cosec^2 a + 2 sin a cosec a = 4

sin^2 a + cosec ^2 a + 2 sin a * 1/ sin a = 4

sin^2 a + cosec ^2 a + 2 = 4

sin^2 a + cosec ^2 a = 4 - 2

sin^2 a + cosec ^2 a = 2

again squaring both side

(sin^2 a + cosec^2 a )^2 = 2^2

(sin^2 a)^2 + (cosec^2 a)^2 + 2 sin^2 a cosec^2 a = 2^2

sin^4 a + cosec^4 a + 2 = 4

sin^4 a + cosec^4 a = 4 - 2

sin^4 a + cosec ^2 a = 2

proved

GIVEN, x=a and y=4 and the equation is

2x+y=6

=>2*a+4=6

=>2a=6-4=2

=>2a=2

=>a=1

ong>Solution :-

Let us assume that, the given line x - 3y = 0 intersect the line segment joining A(-2, -5) and B(6, 3) in the ratio k : 1 at point P(x,y).

Now the section formula says that, the point which divides the line joining two points (a ,b) and (c , d) in the ratio m : N is :- P(x , y) = (cm + an)/(m + n) , (dm + bn)/(m + n) .

So,

Putting values now, we get :-

→ Coordinates of P(x, y) = (6k - 2)/(k+1), (3k - 5)/(k+1)

Now, we have also given that, P lies on x - 3y = 0 .

→ x = 3y

Or,

→ (6k - 2)/(k + 1) = 3{(3k - 5)/(k + 1)}

(k + 1) will be cancel from both denominators,,

→ 6k - 2 = 9k - 15

→ 9k - 6k = 15 - 2

→ 3k = 13

→ k = (13/3)

Therefore,

→ REQUIRED Ratio = k : 1 = (13/3) : 1 = 13 : 3

Now,

→ Coordinates of P(x, y) = (6k - 2)/(k+1), (3k - 5)/(k+1)

Putting value of k = (13/3) , we get,

→ x = { 6*(13/3) - 2 } / (13/3 + 1)

→ x = ( 26 - 2 ) / {(13 + 3) / 3}

→ x = 24 * 3 / 16

→ x = (3 * 3)/2

→ x = (9/2)

and,

→ y = { 3*(13/3) - 5 } / (13/3 + 1)

→ y = ( 13 - 5 ) / {(13 + 3) / 3}

→ y = 8 * 3 / 16

→ y = (3/2)

Hence, Coordinates of P are (9/2, 3/2) .

HOPE it HELPS you mark my ans as brainlest

ong>Given :- Which gives the best estimate and the EXACT product of (5.9)(8.28) ?

A) estimate: 40; exact product: 48.852

B) estimate: 48; exact product: 48.852

C) estimate: 400; exact product: 488.52

D) estimate: 480; exact product: 488.52 .

Solution :-

we know that, :-

When rounding to the NEAREST hundred, look at the tens digit of the number.

If that digit is 0, 1, 2, 3, or 4, you will round down to the PREVIOUS hundred. { The hundreds digit does not change.}

If that digit is 5, 6, 7, 8, or 9, you will round up to the next hundred. { The hundreds digit increases by one.}

All rest digits changes into 0.

So,

→ Estimate value of 5.9 = 6

→ Estimate value of 8.28 = 8

Than,

→ Estimate product = 6 * 8 = 48.

and,

→ Exact value = 5.9

→ Exact value = 8.28

Than,

→ Exact product = 5.9 * 8.28 = 48.852 .

Hence, Option (B) is correct . estimate: 48; exact product: 48.852.

=>(1/√2)(1/2)+(1/√2)(√3/2)

=>(1/2√2)+(√3/2√2)

=>(1+√3)/2√2

Sin 45°Sin30°+Cos45°Cos 30°

Cos45°Cos 30°+Sin 45°Sin30°

Here, A=45° ,B=30°

This is in the FORM of

Cos A Cos B+Sin A Sin B

We know that

Cos A Cos B+Sin A Sin B=Cos(A-B)

Cos45°Cos 30°+Sin 45°Sin30°=Cos(45°-30°)=Cos15°

Cos 15°=(1+√3)/2√2

ong>Answer:

In geometry, a line segment is a part of a line that is bounded by TWO distinct end points, and contains every point on the line between its ENDPOINTS. A closed line segment includes both endpoints, while an OPEN line segment excludes both endpoints; a half-open line segment includes EXACTLY one of the endpoints.
