shealah · Answer

I am pretty sure that you add the lengths of the sides to equal the hypotenuse and then solve for x...

anonymous · Answer

3 = 0?

anonymous · Answer

do like this long side square = sum of ther two sides square
 ie x2+4x+4=x2+25
so the sides are 5,x(5.25), x+2(7.25)

shealah · Answer

never mind i think what i was doing was the pythagorean theorem...  xD

anonymous · Answer

well i did the pythagorem theorm, a^2+b^2=c^2, and i got 5^2 + x^2=(x+2)^2

so i then got 25 + x^2=x^2+4x+4 and now i dont kow what to do?

anonymous · Answer

the Pythagorean theorem is 
$$a^2 + b^2 = c^2$$
so i doubt that :P

anonymous · Answer

thats exactly what i just wrote.

anonymous · Answer

but...we need to know two sides lengths to do the Pythagorean theorem
and that last comment was to shealah

anonymous · Answer

yeah I uploaded the picture that has the information

@livethelifewelove is on the right track

anonymous · Answer

$$25 + x^2 = x^2 +4x + 4$$
$$21 = 4x$$
$$\frac{ 21 }{ 4 } = x $$
$$5 \frac{ 1 }{ 4 }$$

anonymous · Answer

thats what I got. but it doesnt seem right at all

turingtest · Answer

well it is

anonymous · Answer

well ohkay then. Thanks for your help.
