Two adjacent angles are on a straight line. One angle has a measure of (5x - 28) ° and the other angle has a measure of (8x)°. What is the measure of the second angle? (1 point)
The sum of two adjacent angles on a straight line is always 180 degrees. Therefore, we can write the equation:
(5x - 28) + (8x) = 180
Combining like terms, we get:
13x - 28 = 180
Adding 28 to both sides, we get:
13x = 208
Dividing both sides by 13, we get:
x = 16
Substituting x = 16 into the expression for the second angle, we get:
8x = 8(16) = 128
Therefore, the measure of the second angle is 128 degrees.
