What are the steps to solving this problem???
The second problem was written wrong. It should have been, If CD= 15, what is the length of AE?
I now understand how to do the first problem. But how do I apply it to solving the second one?
I changed the image to shows the correct question.

Take the problem on the left.Quote:

So
The second problem is supposed to be done using the same principle, but the diagram seems to conflict with the problem? (CD is the whole base, but 10 seems to be only a part of it?)

Indeed, as with the first I think he meant BA = 30, not BE.Quote:

In the second, if DE = 10, then CD can't possibly be 10, so something is wrong.
On the second figure It was written wrong. It's suppose to be If CD=15 what is the length of AE?Quote:
