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)°.

To find the measures of the two angles, we can set up the equation:

(2x + 3) + (x - 6) = 180

Combining like terms, we have:

3x - 3 = 180

Adding 3 to both sides:

3x = 183

Dividing both sides by 3:

x = 61

Now we can substitute x back into the expressions for the angles:

Angle 1: 2x + 3 = 2(61) + 3 = 122 + 3 = 125 degrees
Angle 2: x - 6 = 61 - 6 = 55 degrees

Therefore, the measures of the two angles that make up the straight line are 125° and 55°.
