Question

Please please help please

Answer 1

The answer is AB = BC = 4√2

Answer 2

AB = BC = 4
`√(2)`

Explanation:

This is a 45-45-90 triangle (right isosceles). This means that the side ratio is

1:1:
`√(2)`, where AC is sqrt 2, and AB and BC are 1. Now, we need to plug this into our ratio. If sqrt 2 is 8, then 1 is x.

8/
`√(2)` = x/1 = x

x = 8/
`√(2)` = 4
`√(2)` (rationalized)

AB and BC are both 4 * sqrt 2
