    Oh.

    Um well 48 is incorrect then, it should be 46 degrees. However, this has no effect on the results I got - I didn't use it in my calculations.

    Start by looking there
    \tan(23)=\frac{BD}{BC}

    \tan(69)=\frac{BD+AD}{BC}

    And you know BC.

    So solve for BD then use it in the 2nd to find AD

    Your answer is correct.

    However, 27.0 is closer to 27.039 than 27.1
