Lauren was standing on the pier at the beach approach trying
to find her sister. She spotted her at the water’s edge
at an angle
of depression of 28°. If the pier is 5 yards above the sand, how far down
the beach is Lauren’s sister?
ð XAC = ð ACB (Angle of elevation= Angle of depression)
AB = 5 Yards
BC = ?
Now Tan C= AB/BC
BC = AB/ Tan C
BC = 5 / Tan 28 Yards
BC = 5/.531709 Yards
BC = 9.403632 Yards

There must be a spring in the base that helps the top rise when you depress the button. You will need to remove the base. The manual doesn't mention anything and there is no Service Manual
