Helpp I'm lost I know it's easy but not for me

Step-by-step explanation:

Using the Pythagorean theorem we can solve this problem.

Pythagoras' theorem= hyp^2-side^2

There are 2 sides in this right-angled triangle. Let's name one side "side a" and the other "side b". Side b is what we'll be finding for.

Hypotenuse= 12

Side a= 5

Side b=?

But in this case we already know the value of the hypotenuse so we have to find for a side.

side^2= hyp^2-side^2

Side^2= 12^2-5^2

Side b= 144-25

Side b= 119

Side b= √119

Side b= 11

Therefore Side b= 11

i believe the correct answer is option 4.principalities were small territories that were run by russian rulers.

which statement correctly defines principalities in northern asia in the 1200s? principalities were small territories that were run by russian rulers.
