Answer:
11
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
