  1. Wait patiently for a helper to come along.
  2. Once someone helps you, say thank you and close the thread with:
+close
  1. Feel free to nominate the person for helper of the week in #helper-nominations
  2. Do not ping the mods, unless someone is breaking the rules.
  3. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

Have you tried sketching it

pine arrow
#

i need someone to shopw me the step by step

pine arrow
#

So that we make sure we're on the same drawing

#

cant find my notebook

#

Ok that's still missing some data

#

ab=15

#

ac=38

#

bc= pythagorean it

#

Which would be

pine arrow
#

then what do i do to find bd

#

,w sqrt(38^2 - 15^2)

pine arrow
#

This sketch will be a bit better

#

Anyway, we need to know what does z equal to

#

Better

#

So, do you know the right triangle altitude theorem

#

that’s the diagram?

#

That's a drawing of the problem, yes

#

This is the kind of stuff you should do when you see geometry problems

#

It makes things 100 times easier, for real

#

my diagram is off then

#

no?

#

Nah yours is the same

#

oh ok

#

It just missed a lot of data

pine arrow
#

i will be back soon tennis lesson

#

starting

#

Ok

#

i apologize miguel

#

thank you

#

I have to go to sleep so someone else can come and help you

#

If no one does, just use the theorem that says

#

okay do you wanna write

#

some of the

#

steps down?

#

I'll show you the clues yes

#

$z^2=xy$

$x+y=38$

#

And then you use the pithagoreas theorem in the two small triangles

#

You'll get systems of equations that will let you solve for z

#

wait how does z^2 = cry

#

xy*

#

is that an identity

#

Yes it is the right triangle altitude theorem

#

If you haven't been taught it, you can easily prove it don't worry

#

You get it by showing that both small triangles are similar
