Answer:
BC=48 units
Step-by-step explanation:
we know that
BC=BH+HC
if Line g bisects line segment BC
then
BH=HC
substitute the given values and solve for x
4x=24
x=6
Find the value of BC
BC=BH+HC
BC=4x+24
substitute the value of x
BC=4(6)+24
BC=24+24=48 units
Note In this problem it was not necessary to find the value of x, the calculation was done for didactic purposes.
