Let's denote the two numbers as x and y. Since their sum is 77, we can write the equation x + y = 77. Given that their difference is 29, we have the equation x - y = 29. By solving these two equations simultaneously, we find that the two numbers are 53 and 24.
The smaller number is (74-16)/2 = 58/2 = 29
