### Similar triangles

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

### Re: Similar triangles

triangle ADE = 81 makes no sense. Do you mean ADE = 81 degrees or something?

A logarithm is just a misspelled algorithm.

### Re: Similar triangles

I tried doing it that way. Let's say x = triangle ABC

ADE / ABC = 3 / 7

81/x = 3/7

x = 189

### Re: Similar triangles

Did you say that D is along AB and E is along BC?
If so, then DE is parallel to AC, not BC.
