Answer 1

first, you'd have to provide some more information.

Answer 2

i can´t post links sadly.

Answer 3

geez - just describe the diagram.
It must have some angles and lengths specified.
Review similar triangles, and what it means to be similar.

and actually, you can post links. Just remove the leading h t t p stuff, up through the two slashes
