(All the problems are here in this link as I had some problem trying to insert images.)

Which problem do you need help on, or all of them?

This is an aops exam isn't it?

I would like help with all of them if it's possible, thanks!

1. 30, 540 subtracted from the angles results in 30

2. 6, s=sqrt2*d/2, solve for d

7. regular measure = 120 for hexagon, square =90

CAB=30, (180-30)/2=75, 180-75=105

105+30=135

180-135=$45$

Thank you so much!
