Question 661174: I have a math problem on my homework, and its a bunch of angles. they give you an equation for two of them that are alternate exterior to eachother, and a varible where it is vertical to the top exterior angle. I dont know how to set up the equation to solve it Answer by solver91311(24713) (Show Source):
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.
