Question

the sum of the square of two number is 386. if one of the number is 5, then other number will be

Answer 1

let the other number be x
5²+x²=386
x²=386-25=361
so x= root 361=19
so the other number is 19

Answer 2

hi

let the 2 numbers be x and y

The sum of the square of two number is 386

so,

lets form an euqation

x² + y² = 386

one number is 5

so let y be 5

now,

x² + 5² = 386

=>x² + 25 = 386

=>x² = 386 - 25

=>x²  =  361

=> x = √361

the √361 is in the photo given below

=>x = 19

hence the other number is 19

hope it helps u
