Answer:
13
Step-by-step explanation:
We now that the two angles are equal due to them being vertical angles. This way, we can safely set them equal to each other.
4x - 14 = 58
To find what x equals, we first need to get x by itself. That means now we have to add 14 on both sides, leaving us with:
4x = 72
Now we divide 4 on both sides:
x = 13
