Question 661174
<font face="Times New Roman" size="+2">


Alternate exterior angles are equal in measure and vertical angles are equal in measure.  So if you have a pair of alternate exterior angles or a pair of vertical angles whose measures are denoted by algebraic expressions, just set the two expressions equal to each other and solve the equation.  Once you have a value for the variable, substitute back into the expressions -- two reasons:  you get the measures of the angles that way, and you double check to see that you did your algebra correctly when you solved the equation.
