The Problem:
The triangles given (see video) are proportional.  Do the following:  a) solve for the unknowns by using proportions and b) state the scale factor between the two triangles.  Express all answers exactly. Figures are not necessarily drawn to scale. Show your work. 










The Solution: x=84/5
y=30 
Scale Factor =2/5 or 5/2
