Answer:

BC = 9

Explanation:

The Line BE = BC + CD + DE

The Line BE = X + 25.

The Line BC = 9 + X

The Line CD = 5

The Line DE = X + 11

Therefore

BE = BC + CD + DE

BE - CD - DE = BC

(X + 25) - (5) - (X + 11) = 9 + X

X + 25 - 5 - X - 11 = 9 + X

9 = 9 + X

0 = X

So

BC = 9 + X

BC = 9 + 0

BC = 9
