    okay you know that the big triangle has the length of DE as 15units and the little triangle has the length of the corresponding side as 5units, so how did you get from 15 to 5? you divide by 3. so you would do the same for side DF since it corresponds with side PR or x. so divide 21 by 3 and get x! tah dah! yay math! jk
