Answer:
x = 49.66667
Explanation:
Ok so we're working with vertical angles. Vertical angles are ALWAYS congruent (equal)
So, set up the equation 148 = 3x - 1 since these angles are congruent.
Now do the algebra. Add 1 on both sides. Now you're left with 149 = 3x.
Divide 3 on both sides, which gives you 49.66667.
Um, this is a weird number actually so I'm sorry if it's wrong.
