<PRE><B>Question 578233</B>

Set the equations equal to each other, since the angles on either side of two intersecting lines must be equal:

10x+6 = 12x - 5

11 = 2x

x= 11/2 or 5.5, plug this back in to either one to get the angle

10(5.5) + 6 = 55+6 = 61 degrees

12(5.5) - 5 = 66-5 = 61 degrees &amp;#8730;
