Trig Help again?

0 ⤊

Points A and B and points C and D are vertices of a trapezoid. Length of AD = 5, CD = 21, AB =10. Angle C = 12 degrees, 50 minutes. Angle D =60

There is a vertical line from A to C

A and B on top. D and C on bottom.

Please help. I know you need to use law of cosine, but I get confused and need help. Please explain what you did. Thank you
