Question

The sum of squares of two numbers is 145. If square root of one number is 3,
then find the other number.
​

Answer 1

Answer:

Let the first number be x and

the second number be y

Given that,

x

2

+y

2

=145

...(1)

x

=3

...(2)

then, using equation (2) squaring

both sides

(

x

)

2

=(3)

2

x=9

...(3)

Putting the value from equation (3)

in equation (1)

(9)

2

+y

2

=145

81+y

2

=145

y

2

=145−81

y

2

=64

$\bf \underline \red{To \ Find} :⇢$

• Other number.

⠀⠀⠀⠀⠀⠀

$\small \bf \underline \red{Given} :⇢$

• The sum of squares of two numbers is 145. If square root of one number is 3.

⠀⠀⠀⠀⠀⠀

$\bf \underline \red{Solution} :⇢$

• Let the 1st number be X

• Let the 2nd number be Y

⠀⠀⠀⠀⠀⠀

As Per 1st Condition :-

• x² + y² = 145 --------------- 1

As Per 2nd Condition :-

• x = 3 ---------------- 2
• ( x )² = ( 3 )²
• x = 9

∴ X = 9 ------------ 3

⠀⠀⠀⠀⠀⠀

Putting the value of equation 3rd in equation 1st

• ➜ 9² + y² = 145
• ➜ 81 + y² = 145
• ➜ y² = 145 - 81
• ➜ y² = 64
• ➜ y = 8

⠀⠀⠀⠀⠀⠀

$\bf \underline \red{Hence}..,$

• The Other number is 8
