Which are the "similar" triannles in the figure?

Unfortunately there is no metion of similar triangles, I have to work with what is gicen in the figure and I don't know where to start. However, there are answers at the back of the book but we are asked to prove or show that x=mtan(A)sec^2(A) and y=mtan^2(A)sec(A).

You are supposed to observe the drawing and analyze.

There are 3 right-angled triangles that share the angle A. Those are all similar triangle. Why?

There are two more triangles that are similar to these. Which are those? Why?

What theorem do you know about ratios of the sides of similar triangles?
