Best ResponseYou've already chosen the best response.0As hetero mentioned \[15^2 +x^2=25^2\] so you need to solve for x here first

Best ResponseYou've already chosen the best response.0The formula is what ever, but you must understand what it means and how to find the variables. In the equation \[a^2+b^2=c^2\] c is the longest side often called the hypotenuse, and a and b are the legs of the triangles. dw:1438608431801:dw

Best ResponseYou've already chosen the best response.0Ok when we do algebra, to isolate a variable we often use the opposite operation of what already exists and do it to both sides. So we have \[15^2+x^2=25^2\] and we want x^2 on it's own, so lets start off by moving the 15^2 to the right side, and remember what we do to one side we must also do the other. dw:1438608573299:dw
