  1. Ask your question and show the work you've done so far. If you've posted a screenshot of a question, specify which part you need help with.
  2. Wait patiently for a helper to come along.
  3. Once someone helps you, say thank you and close the thread with:
    +close
  4. Feel free to nominate the person for helper of the week in #helper-nominations
  5. Do not ping the mods, unless someone is breaking the rules.
  6. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

  1. We are given the area of rectangle ABCD. Using this fact, what is the area of triangle ACD?
  2. Considering edge AC of triangle ACD, what role does DM play in triangle ACD?

l * b = 48
AC = 10
sqrt((l^2 + b^2)) = 10
l^2 + b^2 = 100
b = 48/l
sqrt(b^2) = sqrt(100 - l^2)
b = 10 - l
l^2 + (48 / l)^2 = 10^2
l^2 + (48 / l)^2 = 100
l^2 + (48 / l)^2 = 100
(l^2)^2 + (2304 ) = 100 * l^2
100 +- sqrt(10000 - 9216) / 2
100+-28/ 2
answers will be 128/2 = 64 and 72/2 = 36
as we squared it
we need to root the answers so
sqrt(36) = 6
sqrt(64) = 8

l = 8
so b = 6

#

DMC = 48/2 = 24

#

h = DM

#

5h = 24

#

10h = 48

#

h = 48/10 = 4.8

#

DM = 4.8

**When helping people, please do not dump the full solution. **
Remember that these people are trying to learn concepts, and our goal should be to reinforce them. Giving them a solution will not help.

**Instead, give them hints and guide them toward the correct solution. **
You can ask things like "what part did you get stuck on?" or "what have you tried so far?" or give them a small starting hint. This ensures better learning. For more tips, reach out to Schlaumau (@schlaumau).
