Let's say m<D = x°.

Since m<B = 55° and the sum of angles in a quadrilateral is 360°, we can use the formula:

m<B + m<D + m<C + m<A = 360°

Substitute the values we know:

55° + x° + m<C + m<A = 360°

Now simplify:

x + m<C + m<A = 305°

Since we don't have any other information about the other angles, we can't determine the exact value of m<D unless we are given more information. So, the answer is none of the above options.

The correct answer is 70°.
