Question

Tell whether the given side lengths of a triangle can represent a right triangle.

Answer 1

9,10,and 15

Answer 2

6,10,and 2 to the sqrt 34

Answer 3

@mathstudent55

Answer 4

i would say no to the first set of numbers

Answer 5

yes cuz it would be obtuse?

Answer 6

You can try putting the numbers into the Pythagorean theorem and see if it works. Or, you can reduce the numbers by their greatest common factor and see if it reduces down to one of the common right triangles

Answer 7

probably would be :)

Answer 8

but i dont get the next question with the sqrt

Answer 9

6,10,and 2 to the sqrt 34
this set would be a right angle triangle

Answer 10

\[\sqrt{x}^{2}\]
would be??

Answer 11

?

Answer 12

\[(2\sqrt{34} )^{2}\]

Answer 13

yes so is that the longest side?

Answer 14

how do u know when it is the longest side?

Answer 15

it would be x because a sqrt cancels out a square

Answer 16

its like saying what is the longest? 2 4 6..
you just know!!!
square them all and see which is the longest side

Answer 17

6...

Answer 18

wait so it is the longest side..

Answer 19

Try the numbers in the Pythagorean Theorem. Always use the largest number as the hypotenuse. If it makes it true, then it is a right triangle.
First example: 9, 10, 15
Is 9^2 + 10^2 = 15^2?
Is 81 + 100 = 225?
Is 181 = 225?
Answer is no, so 9, 10, 15 do not represnt the sides of a right triangle.

Answer 20

yea it is the longest side

Answer 21

yes

Answer 22

If so, that is 6, 10 and 2 times square root of 34, not 2 to the sqrt 34.

Answer 23

yea yeah thats wahat i meant..

Answer 24

Try again just like before. First, if you have a calculator, make sure 2*sqrt(34) is larger than 10. I checked and it is.
Is 6^2 + 10^2 = (2*sqrt(34))^2 ?

Answer 25

6^2 + 10^2 = (2*sqrt(34))^2
36 + 100 = 4*34
136 = 136
Since this is true, that means 6, 10, and 2*sqtr(34) are the sides of a right triangle.

Answer 26

(2*sqrt(34) this is like 5. something..

Answer 27

not really

Answer 28

huh....than what is it? cuz im typing it in my calculator...

Answer 29

i would be 11.66......?

Answer 30

it*

Answer 31

how did u get that?

Answer 32

im typing it but.....it sais 5.something

Answer 33

Square root of 34 is 5.83..., 2 * sqrt(34) = 11.66... which is greater than 10

Answer 34

OH!

Answer 35

now i get it..

Answer 36

I HAVE ALOT OF OTHER QUESTIONS PLEASE HELP ILL TAG U GUYS!! K??

Answer 37

sure if i get a medal :D
