Question

Can someone please help me on this and explain if you can!

Answer 1

x =
`11√(2)`

y =
`11√(2)`

Explanation:

the ratio of the sides of a 45 - 45 - 90 triangle is shown at the bottom of this answer.

as you can see, it is x:x:
`x√(2)`

The side given is x
`√(2)`, so you have:

`x√(2)=22`

divide both sides by
`√(2)`

x =
`22/√(2)`

multiply this by
`√(2) /√(2)`

`x = 22√(2)/2`

`x=11√(2)`

y is also equal so y =
`11√(2)`
