you already know the pythagorean theorem?

yes

anonymous · Answer

$\large (side1)^2+(side2)^2=(hypotenuse)^2 $  
since you know a side and the hypotenuse, can you solve for side1 ?

always draw a picture and include the information so you can see if its a subtraction or addition question.

|dw:1346011135541:dw|

needing to find a shorter side then its a subtraction question

then using Pythagoras 

$$x^2 = 10^2 - 8^2$$
