two adjacent angles are on a straight line. one angle has a measure of (5x-28)
Since the two adjacent angles are on a straight line, their measures must add up to 180 degrees (because a straight line forms a straight angle, which measures 180 degrees).
Let's call the other angle y.
Therefore, we can write the equation:
(5x-28) + y = 180
Simplifying, we get:
5x - 28 + y = 180
To solve for y, we need more information.
