@YanaSidlinskiy
To find the length of a, you calculate the difference between the y values. In other words, you go from -4 to -2, which is a distance of *how many units?* For b, it's the same thing except with x values. You go from 1 to 3 which is how many units?
umm...3 units
Once you find the difference between those, you need to square them, using: a^2 + b^2 = c^2 (where c is the hypotenuse) a^2 + b^2 = (distance between points)^2
There's 3 units and what's the other one?
2?
3^2 is 9 2^2 is 4 4+9 is 13.. Square root of 13 is about 3.61
So that is it?
@Elsa213 @ShadowLegendX Is that right? Yes I think so
@YanaSidlinskiy Are you trying to solve for this, like it's a right triangle Using Pythagorean's Theorem?
Yea... Don't tell me I'm wronggggg
I won't, but I'll do it correctly
So it's wrong?
thank you for trying Yana
I mean aren't you supposed to use and draw it in like a right triangle for it to be easier?
(-2,-4) (3, 1) (x, y) The difference between both the x, and the y, is 5 units. a and b, in a^2 + b^2 = c^2, would both be 5.
So that's where you square them both? And then finish it off like I did?
\[a^2 + b^2 = c^2\] \[5^2 + 5^2 = c^2\] \[25 + 25 = c^2\] \[50 = c^2\] Take the root, of both sides \[c = \sqrt 50 \rightarrow c = 7.07106781187\]
oh man im getting a headache....i so dont like math lol
What part do you not understand?
just the last part
Hey it's Pythagrean Theorem Or however you spell it lol.. THat's what we just did except with different numbers....
We used Pythagorean Theorem, which is \[a^2 + b^2 = c^2\] Where, a and b are the two sides, and c is the hypotenuse, or the sloped line that we are solving the distance for
ugh and i am no were near finishing my work i have over 50 questions and i only have 24 done ;_;
okay... i get that
We just found the two sides by observing the coordinates, then solved for the third side
So the answer is.....
7.18 .....
If you understood this, you would know I gave it to you 5min ago ;_;
Hey I understood Ig? Lol
c = 7.07
rounded to two decimal points
oh....srry im a little slow on the uptake :P
