3: Find x
Solution: x = 5
a2 + b2 = c2
a=3
b=4
c=x
32 + 42 = x2
9+16 = x2
25 = x2
sqrt(25) = x
5 = x
x = 5

The forums are retiring in 2021 and are now closed for new topics and comments.

X can also be -5

Lengths can't be negative.

You never mentioned lengths.

x was the side-length of a "3-4-5" right triangle.

Never said that

This was in response to the group photo.

What group photo?

Thats a standard Pythag triangle isn't it?

Well, the question did not state "give the value of x".

Yes. I liked Prony's answer. It showed creativity and an certain amount of Smart Ass. "Find x", "It's Here! -->" lol

Well, it is not my answer. There is a whole exam paper full of those type of ansvers. I'll see if I can put the link up.

It said "3. Find x"

Holy crap you guys make my head hurt :P LOL

a2 + b2 = c2
a=3
b=4
c=x
By Pythagorean theorem -- 3-4-5 triple
x=5

using less lines! :P -- Curious, why did you post this?

I was bored, and the picture for the Math Group was this problem, so I solved it. Boredom is the spice of life :-P
