Answer:
x=6, ab=bc=61, ac=122
Step-by-step explanation:
first of all
in the pic or given we have
that b is midpoint
so
ab=bc
and also
2ab=2bc= ac
so
10x+1=8x+13
10x+1.......eq(1)
8x+13.......eq(2)
by equating the value of x
we have
x=6
so putting value of x in eq
1 and 2
we get
ab=bc=61
by multiplying it with 2
we have ac=122
so i that is the right answer
