Question 1023067: http://prntscr.com/aaio56
So, I'm pretty sure they're congruent because the angles are congruent and corresponding sides are proportional. However, I can't find the scale factor. To find the scale factor, our teacher wants us to set up our problem as a ratio. For eg BC/YZ. I just can't figure that out.

Question 1025182: First off, sorry if I put this under the wrong section, wasn't 100% sure where it belongs.
Problem: A triangular lot has two sides of length 100m and 48m as indicated in the figure below. The length of the perpendicular from a corner of the lot to the 48m side is 96m. A fence is to be erected perpendicular to the 48m side so that the area of the lot is equally divided. How far from A along segment AB should this perpendicular fence be constructed? Give your answer in simplest radical form AND rounded to the nearest tenth of a meter.

Help on this would be VERY much appreciated. I'm quite confused on the wording itself, all I've found out so far is that the area of the triangle is 2304m and that segment AD is 28m using pythag. thm. From this I also know that segment DB is 20m and that segment CB must be square root of 9616. This is where I get stuck and don't know how to advance ;l
