Two adjacent angles are on a straight line one angle has a measurement of 5X -28° and the other angle has a measurement of 8X what is the measurement of the second angle
Since the two adjacent angles are on a straight line, their sum must be equal to 180 degrees. Therefore, we can set up the following equation:
(5X - 28) + 8X = 180
Combining like terms, we get:
13X - 28 = 180
Adding 28 to both sides:
13X = 208
Dividing by 13:
X = 16
Now, we can substitute X back into the expression for the second angle:
8X = 8(16) = 128
Therefore, the measurement of the second angle is 128 degrees.
