If i am correct n= the days so with the days adding up day 10 juan would have 55 of the 100 candies, day 11 he would have 66. The statement said at least 64, so it would have to be 64 or the closet amount to 64 but it cannot be lower than 64. So there for 66 is the closest to the given amount, and in order for juan to get 64 he would need to take candies out for 11 days.
So a triangle is always 180°. If one angle is 90° then we can subtract that from the 180° to find out how much the other two will be. 180°-90°=90° So the other two angles added together will have to equal 90°.
