n - the larger of two i ntegers
m - the smaller of two integers
n + m = 74 → n = 74 - m
n = 2m + 26
Therefore we have:
2m + 26 = 74 - m |subtract 26 from both sides
2m = 48 - m |add m to both sides
3m = 48 |divide both sides by 3
m = 16
n = 74 - 16 = 58
Answer: 16 and 58.
They must make up their mind. Either they should never, or else they should always.
Angles 1, 3, and 4 make up a straight line.
Thus, 3x + 90 + 3x - 6 = 180 (angle sum of straight line)
6x - 6 = 90
6x = 96
x = 16
Now angle 1 becomes 3(16) = 48
Angle 1, 2, and 3 also make up a straight line.
Thus, angle 2 + 48 + 90 = 180
angle 2 + 138 = 180
angle 2, therefore, becomes 42. In essence, (A)
