-
- Options were 360, 361, 362 , none of these..
I think answer will be 361 - 9 years agoHelpfull: Yes(10) No(5)
- Hypotenuse=5 , Second side= 4;
so the third side could be 3 - 9 years agoHelpfull: Yes(9) No(0)

- basically triplet are 3,4,5,
5,12 ,13
7,24,25,
8,15,17.....question on consecutive whole number so 3,4,5
we can multiply any digit (digit >0 ) .that will also triplet ..
ex 30,40,50
45,60,75,
300,400,500 - 9 years agoHelpfull: Yes(5) No(1)
- Pythagorean triplets are generated with each "odd number" greater than 1 by using a formula.
If n is an odd number, then Pythagorean triplet = n,n2−12,n2+12.
Here 361 is an odd number. So the triplet is 361, 65160, 65161.
so answer is 361 - 7 years agoHelpfull: Yes(4) No(0)
- option are 1.360 2.361 3.361 4.none of these
correct answer is 2.361
(361)^2 + x^2=(x+1)^2
you solve this u get the answer.

- triplet 3,4,5 satisfing da condition
hypotenus is 5 (given)
so another side 4
and the 3rd side must be multiple of 3...
now choose from the options. - 9 years agoHelpfull: Yes(2) No(0)
- options were 360,361,362,none of these..
answer...none these
y^2+x^2=(x+1)^2
y^2=2x+1
(y,x)=(3,4),(5,12),(7,24),(9,40).........(25,312),(27,364).... - 9 years agoHelpfull: Yes(2) No(0)
- (x+1)--> hypotenuse
x--> base
h--> height
x^2 + h^2 = (x+1)^2
x^2 + h^2 = x^2 + 1 + 2x
h^2 = 1 + 2x
now put the value given in the option in place of h,
the value of h that give the whole no. value of x is the right answer
i.e 361

- In a Right angle triangle the triplets are of form 2m, 2m-1, 2m+1.
where the hypotenuse is 2m+1, so other side would be 2m or 2m-1.
for example m=2, hypotenuse will be 5 and other sides would be 4,3. - 9 years agoHelpfull: Yes(0) No(0)
- Plzz xpln y d ans is 361 mns how???

- If one of the side is A and hyp is B then the thirsd side is always Root Over A+B. Take 4 and 3 Third side will be root 7 and likewise.. .. ...

If n is an odd number, then Pythagorean triplet =

n,n2−12,n2+12.
Here 361 is an odd number. So the triplet is 361, 65160, 65161. - 7 years agoHelpfull: Yes(0) No(0)
