Answer 1

you already know the pythagorean theorem?

Answer 2

yes

Answer 3

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

Answer 4

always draw a picture and include the information so you can see if its a subtraction or addition question.



needing to find a shorter side then its a subtraction question

then using Pythagoras

\[x^2 = 10^2 - 8^2\]
