Step-by-step explanation:

If the two triangles are similar, you can set up similar ratios and set them equal to each other. For example, you can set up an equation as follows:

first rise/first run = second rise/second run

OR

first rise/second rise = first run/second run

There are many takes on this method. I chose to set it up as follows:

24/27 = 16/x

Now, simply solve for x by cross multiplying!
