I got 12.7. My math was all over the place but I first found CB which was 10.3923. Then I used 10.3923/Sin(55) and got 12.6866 or in 3 sig figs 12.7. I went on to check my work by finding the length of DB and used the 7.2767/cos(55) and got 12.6866 again. Hope that makes some sense. Always check my work with what you’ve been working on in class.
