Answer 1

Explanation:

Compare this to a similar figure with hypotenuse √2 and leg lengths all 1.

Write and solve an equation of ratios, as follows:

x 10

------ = ------

1 √2

10√2

'then x = -------- = 5√2

2

Answer 2

`\huge{ \bold{ \bigstar \: pythagoras \bigstar}}`

Pythagoras :

`{10}^(2) = {x}^(2) + {x}^(2)`

`100 = 2{x}^(2)`

`100 / 2 = {x}^(2)`

`50 = {x}^(2)`

`x = √(50)`

`x = √(25 * 2)`

`\red{x = 5 √(2) }`
