Question

Help Solve please and explain find X and Y

Answer 1

y =
`(9)/(2)`
`√(2)`

x = 9

Explanation:

this triangle is isosceles because the base angles are each 45°

the ratio of sides in a 45-45-90° triangle are 1 : 1 :
`√(2)`

so 'y' is going to also be
`(9)/(2)`
`√(2)`

'x' will be
`√(2)` multiplied by
`(9)/(2)`
`√(2)` which will be:

`((9x2))/(2)` = 9
