    This is too vague. do you have a drawing? I tried to make one from your numbers, but there are too many possibilities.

    Draw a picture. You have TWO common points between the two triangles. They share C and E. You know the lengths of two sides and one angle of each...right angles. CD is (3^2+9^2)^(1/2)

    You cannot. You just know that the distance between the two triangles is 3 connected by a line from B to E, BE=3.

    Sorry. You aren't clueless. You've not been given good information.

    Draw a picture. You'll see what I mean. If you can, ALWAYS draw a picture of the problem.
