Problem C
James is using a clinometer to determine the horizontal distance
between his on-site office and David's office. James stands at his office
window & calculates the angle of depression to David's office window
to be 250. James is at an elevation of 80ft and David's office is at an
elevation of 36ft. Detennine Ihe horizontal distance between the two
offices.

In today's task, you will work with a partner to complete as many of the II problems you're given by the end of
the class period. You will need to show your work for each problem on this sheet of paper as this is what you
will turn in at the end of the class period. You will be assessed for accuracy for each problem and not permitted
to progress to the next problem until your current problem is solved correctly.
