Given: AC = BC ABC is an isoceles triangle AB2= 2 AC2To prove: ABC is a right triangleProof: For ABC to be a right triangle, it should satify pythagoras theoremi.e AB2= AC2+ BC2Now, AC = BC (given)On substitution, we findAB2= 2 AC2, which is true according to the question.So, the given sides form pythorian triplets.Hence ABC to be a right triangle right angled at C.

Subhash Chandra Bose contribution in freedom, achievements.:1. Subhash Chandra Bose was a freedom fighter who played a very important role in getting the freedom from British. Subhash Chandra Bose joined Congress after resigning from Civil services but he did not like the idea of Mahatma Gandhi's opinion of non-violence.2.Netaji Subhash Chandra Bose is important because India got freedom due INA formed by him. ... Because of this trial indian army which was loyal to British turned against them. This made it Iimpossible for British to continue in India. This fact was accepted by Atlee when he came to India in 1955.3.Bose joined the non-cooperation movement that was started by Mohandas K. Gandhi, who had made the Indian National Congress a powerful nonviolent organization

Please like my comment 😢😭😭😭😭

60+70=110130-110=20

60+70=110130-110=20 is the right answer of the following

60+70=110130-110=20

For compound interestA = P(1 + R/100)^n =12500(1 + 12/100)^3 =12500(1 + 3/25)^3 = 12500(28/25)^3 = 12500(1.12)^3 = 12500(1.404) = 17550

He has to pay Rs 17550 to close the loan

I don't know this question

9.125%Rate is the right answers

9. 125 percent right answer

9.125% is correct answer

9.125 is the correct answer

Amount = P{1 + (r/100)}^n

or, we know the values of P, r, n.

P = Rs 12500, r = 12% and n = 3yrs.

CI = 12500{1 + (12/100)^3

or, 12500{(112 x 112 x 112)/(1000000)}

or, Rs 17561.6 (Ans)

Therefore, Sameerrao has pay to pay Rs 17561.6 to clear his loan

Like my answer if you find it useful!

Given are , Principal = ₹ 8000

Money paid by man(Amount) = ₹8640

So, Simple Interest = Amount - Principal = 8640-8000=₹640

Time is given as = 320 days = 320/365 years = 64/73 years .

By using formula, R = SI * 100 / T * P = 640*100*73/64*8000 = 9.12% Per Annum.

Answer : Hence, rate of interest = 9.12% p.a

A natural disaster is a major adverse event resulting from natural processes of the Earth; examples are floods, hurricanes, tornadoes, volcanic eruptions, earthquakes, tsunamis, and other geologic processes

National securityis thesecurityof anation state, including itscitizens,economy, and institutions, which is regarded as a duty of government.

Originally conceived as protection againstmilitary attack, national security is now widely understood to include non-military dimensions, including the security fromterrorism,crime,economic security,energy security,environmental security,food security,cyber securityetc. Similarly, national security risks include, in addition to the actions of othernation states, action byviolent non-state actors,narcotic cartels, andmultinational corporations, and also the effects ofnatural disasters.

Governments rely on a range of measures, includingpolitical,economic, andmilitarypower, as well asdiplomacyto safeguard the security of the nation state. They may also act to build the conditions of security regionally and internationally by reducingtransnationalcauses of insecurity, such asclimate change,economic inequality,political exclusion, andnuclear proliferation.

Anaturalhazard is athreatof anaturallyoccurring event will have a negative effect on humans. This negative effect is what we call anaturaldisaster. In other words when the hazardousthreatactually happens and harms humans, we call the event anaturaldisaster.

9x - 5y = - 19x = 5y - 1x = (5y - 1)/9.......(1)

4x - 3y = - 2.........(2)

Put value of x from eq(1) in eq(2)4*(5y - 1)/9 - 3y = - 220y - 4 - 27y = - 18-7y = - 18 + 4-7y = - 14y = 14/7 = 2

Now, put value of y in eq(1)x = (5*2 - 1)/9 = 9/9 = 1

Therefore,Value of x = 1, y = 2

let the present ages of A and B be a,b

=> age of A and B five years ago is a-5 and b-5

ratio of a-5 and b-5 is 5/7=> a-5/b-5 = 5/7 => 7a-35 = 5b-25=>7a-5b = 10

now 5 years from present there ages will be a+5, b+5

now sum of their ages will be (a+5)+(b+5)= a+b+10

now from 1st equation a = (10+5b)/7

put this in a+b+10 = (10+5b)/7+b+10= 10+5b+7b+70/7=12b+80/7

now check for values of b.

12b+80/7 = (7b+70)/7 + 5b+10/7= b+10 + (5b+10)/7

now for (5b+10)/7 to be integer.ao check the values of b.

ABCD is a parallelogram .

Point E is on the ray AB such that

BE = AB .

To prove : BF = FC

Proof :

i ) AB = DC [ opposite sides ]

AB = BE ( given )

DC = BE --- ( 1 )

ii ) In ∆DCF and ∆EBF

<FDC = <FEB [ alternate angles ]

DC = BE ( S ) [ from ( 1 ) ]

<DFC = <EFB [ veritically opposite angles ]

Therefore ,

∆DCF is congruent to ∆EBF

[ ASA congruence Rule ]

CF = FB [ CPCT ]

1. Climate change

Changes in climate throughout our planet's history have, of course, altered life on Earth in the long run — ecosystems have come and gone and species routinely go extinct.

But rapid, manmade climate change speeds up the process, without affording ecosystems and species the time to adapt. For example, rising ocean temperatures and diminishing Arctic sea ice affects marine biodiversity and can shift vegetation zones, having global implications.

Overall, climate is a major factor inthe distribution of speciesacross the globe; climate change forces them to adjust. But many are not able to cope, causing them to die out.

2. Deforestation and habitat loss

Deforestation is a direct cause of extinction and loss of biodiversity. An estimated18 million acresof forest are lost each year, due in part to logging and other human practices, destroying the ecosystems on which many species depend.

Tropical rainforests in particular, such as theAmazon, hold a high percentage of the world's known species, yet the regions themselves are in decline due to humans.

3. Overexploitation

Overhunting, overfishing and over-harvesting contribute greatly to the loss of biodiversity, killing off numerous species over the past several hundred years. Poaching and other forms of hunting for profit increase the risk of extinction; the extinction of an apex predator — or, a predator at the top of a food chain — can result incatastrophic consequencesfor ecosystems.

5. Pollution

From the burning of fossil fuels (releasing dangerous chemicals into the atmosphere and, in some cases, depleting ozone levels) to dumping19 billion pounds of plasticinto the ocean every year, pollution completely disrupts the Earth's ecosystems. While it may not necessarily cause extinction, pollutants do have the potential to influents species' habits.

For example, acid rain, which is typically caused by the burning of fossil fuels, can acidify smaller bodies of water and soil, negatively affecting the species that live there bychangingbreeding and feeding habits.
