The first poster is not an accurate representation of the painting, but the second poster is an accurate representation because the ratio between the first and original lengths did not equal the ratio between the first and original widths but the second poster's ratios were equal.
Remember that to find distance (or the slope) you need this formula y2-y1/x2-x1. 5+10 = 15
-3+9 = 6 15/6 = 5/2

2
Is ur answer
It has 4 significant figures
I think x = 5, because you need to find the ratio between the two triangles.
