Answer:
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, and x, with the legs = x and the hypotenuse =
.
We have the hypotenuse as 8, so plug it in:
8 =
![x√(2)](https://img.qammunity.org/2021/formulas/mathematics/high-school/zdu54xik2wajk6tmyewmo1dwpjgina1kuc.png)
8/
= x
Multiply both the top and bottom of that fraction by
to get
8
/
![√(2\\)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/gw9mzjys6e9h3fy77ttlncbggxkaxdto2w.png)
=
8
/ 2 = 4
![√(2\\)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/gw9mzjys6e9h3fy77ttlncbggxkaxdto2w.png)
x = 4
, so v and u = 4
