The left and right page numbers of an open book are two consecutive intergers whose sum is 199 find these page numbers

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

well we know there are 4 clubs in 52 cards so it’s replaced so it should be 3/51
