Sum around a triangle

Can you solve this week's puzzle?  Start with "A" and then try "B" if you're up for the challenge.

A)  The triangle below has the numbers 1, 2, and 3 placed at the vertices.  Your job is to place the numbers 4, 5, 6, 7, 8, and 9 along the sides of the triangle (2 numbers along each side), so that the total for each side adds up to 17.  Example:  Let's say you place the numbers 4 and 5 along the side between the 1 and 2.  This would give you a total of 1+4+5+2 along that side.  The total is only 12 and you need each side to add up to 17, so 4 and 5 are not the correct numbers.

B)  This one is trickier.  You are not given any of the numbers.  Your job is to place the numbers 1 through 9 around the triangle in the same fashion as you did for part "A", which means placing a number at each vertex, and 2 numbers along each side.  But for this one, the total along each side must equal 20.  Good luck!
