In the diagram below, BC connects points B and C on the congruent sides of isosceles
triangle ADE, such that triangle ABC
is isosceles with vertex angle A.
If AB = 10, BD = 5, and
DE = 12, what is the length of
BC?
1)9
2) 8
3) 7
4) 6

.25

step-by-step explanation:

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

table a is wierd
