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?(1 point)

To find the measures of the two angles, we set up the equation:
(2x + 3) + (x - 6) = 180
Combining like terms, we get:
3x - 3 = 180
Adding 3 to both sides, we have:
3x = 183
Dividing both sides by 3, we get:
x = 61
Now we can substitute this value back into the expressions for both angles:
First angle: (2x + 3) = (2 * 61 + 3) = 125°
Second angle: (x - 6) = (61 - 6) = 55°
Therefore, the measures of the two angles that make up the straight line are 125° and 55°.
