Answer:

X=7.9

Y=7.9

Step-by-step explanation:

We have that x=y

And form Pythagoras theorem we have

5 \sqrt{5} =  \sqrt{x ^{2} + x ^{2}  }   \\ take \: the \: square  \: of \: the \: two \: sides \\ 125 = 2x ^{2}  \\ x {}^{2}  = 62.5 \\ x = 7.9

Could you help me understand cross sections of three-dimenstional object its harder than it sound.​
umka21 [38]

A section, or cross-section, is a view of a 3-dimensional object from the position of a plane through the object. A section is a common method of depicting the internal arrangement of a 3-dimensional object in two dimensions. It is often used in technical drawing and is traditionally crosshatched.

Cross sections of three-dimensional objects are two-dimensional shapes of various sizes. They may be parallel to a side or base of the object or at an angle to these surfaces. A cross section may resemble the shape of the object’s side or base, or it may have a completely different shape.
