A 180° angle (straight line) is formed by two adjacent angles. One angle has a measure of (2x+3)° and the other has a measure of (x−6)°. What are the measures of the two angles that make up the straight line?

121° and 59° 121 degrees and 59 degrees 129° and 51° 129 degrees and 51 degrees 125° and 55° 125 degrees and 55 degrees 186° and 88°

The measures of the two angles that make up the straight line are 121° and 59°.
