- Wait patiently for a helper to come along.
- Once someone helps you, say thank you and close the thread with:
+close
- Feel free to nominate the person for helper of the week in #helper-nominations
- Do not ping the mods, unless someone is breaking the rules.
- 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
Yes
i need someone to shopw me the step by step
Send it here please
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
38^2 -15^2
then what do i do to find bd
,w sqrt(38^2 - 15^2)
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
So this
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
$z^2=xy$
Miguel
$x+y=38$
Miguel
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
found the solution
