    whenever two lines like this intersect: < abc = < dbe and < abd = < cbe this means that 6x - 7 = 4x + 23 solve for x then plug it in.

    The measure of < ABC is given algebraically as (6x - 7)/ Assuming x = 15, then the measure of <ABC = 6*15 - 7 = ? @leroysgurl15

    You are welcome. Also, note the reason that those two angles are congruent is that they are vertical angles. By a theorem, vertical angles are congruent and therefore have the same measure.
