Question

Can someone help me with this problem

Answer 1

x = 43

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

Answer 2

3x + 14 = 143

3x = 129

X = 43
