Question 946286

How do i solve vertical angles with the equation 2x+50 and 4x+12
<pre>
Vertical or vertically opposite angles are congruent
Since one is: 2x + 50 and the other is: 4x + 12, then we can say that:
2x + 50 = 4x + 12
2x - 4x = 12 - 50
- 2x = - 38
x = {{{(- 38)/(- 2)}}}, or 19
You now substitute 19 for x in any of the 2 expressions to determine the angle.
