they are similar triangles, meaning that their sides are proportional. Based on the photo, it is assumable that x and 20 are proportional, so we can write is as a fraction. Then you can take 12.8 and 16 which are also proportional and say it is equal to 
because corresponding sides yay math woohoo! anyway, you can solve that equation by doing cross products:
you could also do 
, but you may notice that 10 fits into 20 two times so you do not even need to do cross products. y = 8.Find the missing side length for each set of similar figures.

Matt and brian were solving a system of equations. they both noticed that the two lines had the same slope. brian said that because each line in the system had the same slope, the two lines had to be parallel, which meant the solution to the system was "no solution" matt disagreed, and said they should also look at the y-intercepts before determining how many solutions there were. who is correct?
