He needs 1080 I believe so 38 because 1042 divided for 45 museums would be 23.15 meaning it wouldn't be the same amount for all but if they get 38 pictures (1080) and divide it between the 45 museums it would be an even number of 24 so the answer is 38 more pictures
Each triangle has angles and all of those angles add up to 180 degrees total. since both of those angles at the bottom are equal then their angles would each be 70.
