Best ResponseYou've already chosen the best response.0then why don't you try the combination and see if they satisfy the theorem.

Best ResponseYou've already chosen the best response.0I meant square root of 11 is 3.3

Best ResponseYou've already chosen the best response.0huh? why are you making the problem more complicated than it is? They have given you lengths of the three sides of a triangle. All they want to know is if the triangle is a right angled triangle. The way to find out if a triangle is right angled or not is to see if its sides satisfy the pythagorean theorem. That is it. Don't try and make it harder for yourself.

Best ResponseYou've already chosen the best response.0ok so two square roots and one is not... therefore no

Best ResponseYou've already chosen the best response.0Ok I'm not sure... but I came up with 6.6 + 4.4 = 11 by definition: the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs. So again I would say this is not a right triangle ??

Best ResponseYou've already chosen the best response.0yes, you are right. It is not a right angle triangle.

Best ResponseYou've already chosen the best response.0was that right how I did the calculations tho? took square root of 11 times it by two .... the same for square root of 5 times by two and then add ... was that number supposed to add up to 16? to make it a right triangle?

Best ResponseYou've already chosen the best response.0wait...3.3 squared plus 2.2 squared = 10.89 + 4.84 = 15.73 thats close to 16

Best ResponseYou've already chosen the best response.0square root of 4 is 2. that means 2 times 2 is 4. that means \[\sqrt{4} \times \sqrt{4} = 4\]

anonymous

Best ResponseYou've already chosen the best response.0so \[(\sqrt{11})^{2} = \sqrt{11} \times \sqrt{11} = 11\]

Best ResponseYou've already chosen the best response.0the very fact that you are squaring square roots of a number means that you will get the number within the square root. That is the definition of square root.

Best ResponseYou've already chosen the best response.0I don't know... I do know the square root of 81 is 9...

anonymous

Best ResponseYou've already chosen the best response.0yes, square root of 81 is 9. that means that 9 times 9 is 81. similarly square root of 3 is 1.73205081 that means that 1.73205081 times 1.73205081 is 3.

Best ResponseYou've already chosen the best response.0instead of calling it square root everytime, we write it is \[\sqrt{3}\]

Best ResponseYou've already chosen the best response.011 + 5 = 16 therefore it is a right triangle

Best ResponseYou've already chosen the best response.0what is the third side? is it 16 or square root(16)

anonymous

Best ResponseYou've already chosen the best response.0square root of 16 I know is 4

Best ResponseYou've already chosen the best response.0so what does the pythagorean theorem say?

anonymous

Best ResponseYou've already chosen the best response.0I'm confused...... I already said it... I just dont know if these numbers are supposed to add up to something or have all perfect numbers from the roots? UGGGH

anonymous

Best ResponseYou've already chosen the best response.0or the two square roots equal 16? Please be patient with me....

Best ResponseYou've already chosen the best response.0\[(\sqrt{11})^{2} + (\sqrt{5})^{2} = 16 \neq 16^{2}\]

Best ResponseYou've already chosen the best response.0Here is another one.... (√7)2 + (√2)2 = 9 does not equal √9 Not a right triangle
