90 degrees
Step-by-step explanation:
All trapazoids are equal to 360 degrees.
so we can make an equation 2x+x+x=360 (the other corner would also be x because its an unknown value)

you divide into both sides (360/4)
you get 90
Well since each shelf holds 40 you would add up the two shelves to 80 then add 5 on one shelve to get 85. Since he has room for 40 you would subtract 5 and get 35
