Two adjacent angles are on a straight line. One angle is (5x−28)° and the other angle is 8x°. What is the degree value of the second angle?
A: 16°
B: 128°
C: 52°
D: 120°

C: 52°
5x - 28 + 8x = 180
13x = 208
x = 16
so the angles are 5(16)-28 and 8(16), which would be
52° and 128°
The question is not clear what is meant by the "second angle"
according to the sequence they are listed, one would assume it to
be 8x, which would be the 128° angle
13x = 208
x = 16
so the angles are 5(16)-28 and 8(16), which would be
52° and 128°
