Question

Find two numbers in the ratio 4 : 2 such that the sum of their squares is 160

Answer 1

Answer:

first no =4x and second =2x

acc to ques

$({4x})^{2} + ({2x})^{2} = 160 \\ 16 {x}^{2} + 4 {x}^{2} = 160 \\ 20 {x}^{2} = 160 \\ {x}^{2} = 8 \\ x = \sqrt{8} \\ x = 2 \sqrt{2}$

number =

2×x=4√2

and

4×x=8√2
