Two adjacent angles are on a straight line. one angle has a measure of (5x - 28) and the other has a measure of (8x) what is the measure of the second angle?
Since the two angles are adjacent and on a straight line, their sum is equal to 180 degrees. Therefore, we have the equation:
(5x - 28) + (8x) = 180
Combining like terms, we get:
13x - 28 = 180
Adding 28 to both sides, we have:
13x = 208
Dividing both sides by 13, we get:
x = 16
Plugging x back into the equation for the measure of the second angle, we have:
8(16) = 128
Therefore, the measure of the second angle is 128 degrees.
