Question

the sum of squares of two numbers is 145 if the square root of one number is 3 then find the other​

Answer 1

Answer:

Let the first number be x and

the second number be y

Given that,

x2+y2=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+y2=145

81+y2=145

y2=145−81

y2=64

Answer 2

Answer:

8

Step-by-step explanation:

3*3=9*9=81

145-81=64

√64=8Ans
