Step-by-step explanation:
The triangles share the same angle measures, so they are similar triangles. The side lengths of similar triangles are proportional to each other, so we can set up a proportion and solve for n...

16/20 = 24/n now solve for n by cross multiplying
16n = 480
n = 30 (divide both sides by 16)
