3x°−75°−106°=180°
3 x minus 75 minus 106 degrees equals 180 degrees

3x°−75°+106°=180°
3 x minus 75 plus 106 degrees equals 180 degrees

3x°−75°=106°
3 x minus 75 equals 106 degrees

3x°−75°+106°=90°

Answer 1

Vertical angles are equal, which means that the measures of angles 1 and 2 are the same. Therefore, you can set the two angle measures equal to each other to write the equation:

\[ m∠1 = m∠2 \]

Substituting the given measures:

\[ 106° = (3x - 75)° \]

To solve for \( x \), you can rewrite this as:

\[ 3x - 75 = 106 \]

This matches the answer option:

3x°−75°=106°

So, the correct equation to solve for \( x \) is:

3x°−75°=106°
