Question

Answer

Given:
Sum of squares of two numbers is 145.
Square root of one number is 3.

To find:
The other number.

Solution:
Let the two numbers be x and y.
Given, x + y = √145
Also, √x = 3
Squaring both sides, we get
x = 9

Substituting the value of x in the first equation, we get
9 + y = √145
y = √145 - 9

Simplifying,
y = 8

Therefore, the other number is 8.

Hence, the correct answer is option B.

Answer

Answer

Sol)Let the two numbers be = x and y
given = x^2+y^2= 145
since sqrt of x is 3 so x=9
so)9^2+y^2=145
=>81+y^2=145
=>y^2=145-81
=>y=sqrt of 64
therefore y=8

Answer

8

Answer

Let, √a=3
a=9
a^2=81
a^2+b^2=145
81+b^2=145
b^2=145-81
b^2=64
b=8
