Answer 2

Vague question. Do you mean "find the length of side b of the larger triangle?"

Answer 4

I don't think it is a vague question.
I think he just wants to find every term: \(a\), \(b\), \(x\), \(y\), and \(z\).
------------------------------------------------

Every triangle is a 30-60-90 triangle. So, if you look at the
biggest triangle, you can deduce that \(x=7.5\) and \(z=7.5\sqrt{2}\).

Then, look at the smallest triangle at the very left, and you
will find that \(a=3.75\) and \(y=3.75\sqrt{5}\).

Then, \(b=15-a=15-3.75=11.25.\)
