Ms. Salonga needs to deliver ordered cars and assigned Handy Migui to deliver them using a truck. She informed him that the inclined ramp used to unload cars from the truck has a rise of 5m, a run of 12m which is 7m longer than the rise, and is 13m long which is 8m longer than the rise. Therefore, the measurements that allow the cars to be unloaded safely are: the rise is 5m, the run is 12m, and the length of the ramp is 13m.

- 21. Ms. Salonga, an owner of a car company, needs to deliver the ordered cars. She assigned Mr.Castillo to deliver the cars. He usually uses a truck for the delivery and he is also a mechanic. The inclined ramp used for loading cars in a truck is 8m longer than the rise of the ramp. The run is 7m longer that the rise. How long are the three sides of the ramp for the cars to be unloaded safely?
