Question

Whats the answer? A, B, C, or D??

Answer 1

D

Explanation:

This triangle is a 45-45-90 triangle, which is a special triangle! Ooh! That means we already know that the ratio of its sides is
`x√(2)`, x, and x, with the legs = x and the hypotenuse =
`x√(2)`.

We have the hypotenuse as 8, so plug it in:

8 =
`x√(2)`

8/
`√(2\\)` = x

Multiply both the top and bottom of that fraction by
`√(2\\)` to get

8
`√(2\\)` /
`√(2\\)`
`√(2\\)` =

8
`√(2\\)` / 2 = 4
`√(2\\)`

x = 4
`√(2\\)`, so v and u = 4
`√(2\\)`!

Answer 2

C is the correct answer
