This question is really easy but I'm weak in similar triangle.. I dont know how to do it.
In triangle ABC, D and E are in AB and AC respectively such that DE is parallel to BC, AD = 3, DB = 4, and triangle ADE = 81. Determine
1. triangle ABC
2. quadrilateral DBCE
triangle ADE = 81 makes no sense. Do you mean ADE = 81 degrees or something?
A logarithm is just a misspelled algorithm.
oh those are the areas I mean.
So you can do it all alone.

I tried doing it that way. Let's say x = triangle ABC
ADE / ABC = 3 / 7
81/x = 3/7
x = 189
But the answer is 441
Did you say that D is along AB and E is along BC?
If so, then DE is parallel to AC, not BC.
