measure of angle ABC=4x-12
measure of angle ABX=24
BX bisects ABC
solve for X and find the measure of angle ABC
**page 48 # 11 of prentice hall,california geometry**

    What's the problem?

    We know that ABX is half of ABC.
    So, since ABX = 24, ABC = 48

    48 = 4x-12
    60 = 4x
    x = 15

    Not too bad, eh?

    x=15
