(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!
