A pair of vertical angles have equal measures. Therefore, since m∠1 = 106°, we have:
m∠2 = 106°
Since m∠2 = (3x - 75)°, we can set up the equation:
3x - 75 = 106
Therefore, the equation to solve for x is:
3x - 75 = 106
So, the correct answer is A. 3x°−75°=106°.
There is a pair of vertical angles whose measures are m∠1=106° and m∠2=(3x−75)° . What equation can you write to solve for x ?
