3x = 129
X = 43
Answer:
x = 43
Step-by-step explanation:
lines were parallel, then 143 would have to congruent to the vertical angle of 3x + 14
this means that 143 would have to be congruent to 3x + 14
so we can set the equation to 3x + 14 = 143
subtract 14 from both sides: 3x = 129
divide both sides by 3: x = 43
