What is the length of XY?

What is the length of YZ?

Answer 1

XY = geometric mean of XW and XZ

Answer 2

\[\large XY = \sqrt{XW*XZ}\]

Answer 3

\[\large XY = \sqrt{3*7}\]

Answer 4

thank you! but do you do the same thing for yz?

Answer 5

yes !
take the geometric mean of `near segment` and the `entire hypotenuse` :

\[\large YZ = \sqrt{WZ * XZ}\]

Answer 6

plugin the values ^^

Answer 7

okay thank you

Answer 8

what do u get for YZ ? :)

Answer 9

i got 4.58 for both of them

Answer 10

you should get XY = sqrt(21) = 4.58

Answer 11

YZ should be different

Answer 12

oh:/
