${5}^{2} + {x}^{2} = {8}^{2}$

$25 + {x}^{2} = 64$

Subtract both sides 25

$25 - 25 + {x}^{2} = 64 - 25$

${x}^{2} = 39$

Thus :

$x = \sqrt{39}$

$x = 6.245$

Answer:

2.2

Step-by-step explanation:

A kilogram is 2.2lbs so if you weigh yourself and it says you weigh 60k then you multiply 60 times 2.2 you get 132lbs.
