The designers of a skateboard park are building a ramp and need a scaled-down model of one of their ramps. The side view of the actual ramp, labeled JKL, and the side view of the model, labeled PQR, is shown below. What would be the coordinates of a new point R that will make the model version of the ramp similar to the actual ramp? Explain your reasoning using complete sentences.

to be similar means the dimensions need to be proportional
length of JL is 24
$$\frac{24}{12} = \frac{PR}{2}$$
solve for length of PR
then add that to 30 to get point R

haha umm no...thats your job
hopefully i helped you understand the concept
