a^2 + b^2 = c^2
6.5^2 + x^2 = 10^2
42.25 + x^2 = 100

Supplementary angles are angles that together, for an angle of 180°. Straight lines are also 180°, so what you need to look for in this exercise are angles, next to eachother, on the same straight line.
those are:

1,4
2,3
5,6
5,8
6,7
7,8
3,4
so the right answers are option 1 and 2
