Question

Given the following tabulated data for a close traverse in which the lengths of BC and CD have not been measured in the field. Determine these unknown quantities. 
(HINT: Use station B and D as a closing line to create a three-sided polygon then use sine or cosine law to solve for the
missing sides or course.)
