### Net Figures

The numbers 1 up to and including 8 must be put in the circles of the depicted net. However, numbers in neighbouring circles must differ more than 1. So, for example, circles connected to a circle with a 4 may not contain a 3 or a 5.

Think that one was easy? Try this one.
The numbers 1 up to and including 9 must be put in the circles of the second figure in such a way that the sum of the corners of each of the 7 triangles (4 small ones and 3 large ones) is equal.

To answer in the comments, give the numbers in order for each row of the two figures.
