Answer:

  • d = 2√2
  • b = 5√3

Step-by-step explanation:

In these special right triangles, the sides have length ratios ...

  45-45-90: 1 : 1 : √2

  30-60-90: 1 : √3 : 2

This tells us ...

  d×√2 = 4 . . . . . . . . . . relationship between the side and the hypotenuse

  d = 4/√2 = 2√2

__

  b = 5√3 . . . . relationship between the short side and long side
