Answer 2

You want to find the length of lines B and C and lines C and A. Then you can use the Pythagorean Theorem to find the hypotenuse, which will be side AB.

Answer 3

Pythagorean Theorem:
\[a^2 + b^2 = c^2\]

Answer 4

how do i find the length between b and c and c and a though? :)

Answer 5

Lines B and C have the same y-axis, therefore, so you just want to find the difference of the numbers in the x-axis (4 and 2).

Answer 6

ohhhh! okay!

Answer 7

i got 3.61??

Answer 8

when i did pythagorean theorem

Answer 9

Okay so we have Lines B and C equal to 2, and lines C and A equal to 3.

So the Pythagorean Theorem states
2^2 + 3^2 = c^2

Answer 10

We know that two squared = 4 and 3 squared = 9. 4 + 9 = 13. Now you just need to find the square root of 13. And if you look closely, you already have the answer: \[\sqrt{13}\]
