Two adjacent angles are on a straight line. One angle has a measure of%C2%A0 (5x−28)° and the other angle has a measure of%C2%A0 (8x)° . What is the measure of the second angle?(1 point) Responses 120° 120 degrees 128° 128 degrees 52° 52 degrees 16°
Since the two angles are adjacent and on a straight line, their sum must be 180 degrees.
(5x-28) + (8x) = 180
13x - 28 = 180
13x = 208
x = 16
Therefore, the second angle is (8x) = 8(16) = 128 degrees.
The measure of the second angle is 128 degrees.
