Answer:
D
Step-by-step explanation:
If one of the angles of a right triangle is 45*, then the other one will be the same. Therefore, both legs of the triangle will be equal as well.
The hypotenuse of a 45* - 45* -90* triangle is equal to x[tex]\sqrt 2[/tex], therefore x = [tex]\frac{5}{\sqrt{2} }[/tex]
The answer, when plugged into a calculator, will be D. [tex]\frac{5\sqrt{2} }{2}[/tex]
