Question

I need too find the missing side lengths does anyone know the answer!

Answer 1

Explanation:

`sin45=(x)/(4)`
`(sin=(opposite)/(hypotenuse))`

`x=4sin45`

`=(4)/(√(2))`

`=(4)/(√(2))*(√(2))/(√(2))`

`=(4√(2) )/(2)`

`=2√(2)`

`cos45=(y)/(4)`
`(cos=(adjacent)/(hypotenuse))`

`y=4cos45`

`=(4)/(√(2))`

`=2√(2)`
