Question

Find the measurment of line segement
DE and EF?

Answer 1

Explanation:

`n√(2)=10`

Solve for n.

`n√(2) =10\\\\(n√(2) )/(√(2) )=(10)/(√(2) )`

Rationalize the denominator.

`n=(10)/(√(2) )\cdot (√(2) )/(√(2) )\\\\n=(10√(2) )/(2)`

Reduce to lowest terms.

`n=(10√(2) )/(2) /(2)/(2)\\\\n=5√(2)`
