If AB=BC=CD and A=3 and D=14, what is B?

To find the value of B, we can use the fact that AB = BC = CD.

Given that A = 3 and D = 14, we can set up the equation:

AB + BC + CD = AD

Substituting the given values, we have:

3 + BC + 14 = 17

Simplifying the equation, we get:

BC + 17 = 17

Subtracting 17 from both sides, we have:

BC = 0

Therefore, the value of B is 0.
