(2x+3)+(x−6)=180

2x+3=x−6

(2x+3)−(x−6)=180

(x+6)−(2x+3)=180

3x−3=180
3 x minus 3 is equal to 180

Angle 2x + 3 is

Angle x - 6 is
degrees.

Answer 1

Part 1: The two equations that can be used to determine the measure of these two adjacent angles, which add up to 180 degrees, are:

1. (2x + 3) + (x - 6) = 180 (This correctly represents the sum of the two angles.)
2. (2x + 3) - (x - 6) = 180 (This does not correctly represent the angles but can be manipulated correctly.)

So, the correct choice for determining the adjacent angles is:

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

Part 2: Let's solve the first equation:

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

Combine like terms:

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

Now add 3 to both sides:

3x = 180 + 3 3x = 183

Now divide by 3:

x = 61.

Now that we have the value of x, we can find the measures of the angles:

1. Angle $2x+3$:

   • $2(61)+3=122+3=125$ degrees.

2. Angle $x-6$:

   • $61-6=55$ degrees.

Final answers:

• x = 61
• Angle $2x+3$ is 125 degrees.
• Angle $x-6$ is 55 degrees.
