Question

Is this correct? Pythagorean Theorem

Answer 1

Here's my answer:

U(2, 7) X(2, 2)

|2 - 2| = 0
|7 - 2| = 5

0^2 + 5^2 = XU^2
0 + 25 = XU^2
√25 = XU
5 = XU
XU = 5

Answer 2

your second line is wrong
U is (-2,7) not (2,7)

Answer 3

so we have
|-2-2| = 4

Answer 4

Oh, yeah that's right.
Okay, so this would be correct then:

U(-2, 7) X(2, 2)

|-2 - 2| = 4
|7 - 2| = 5

4^2 + 5^2 = XU^2
16 + 25 = XU^2
√41 = XU
6.40 = XU
XU = 6.40
