A sailor sights both the bottom and top of a lighthouse that is 20m high and stands on the wedge of a cliff. The two angles of elevation are 35 degrees and

42 degrees. To the nearest meter, how far is the boat from the cliff?

first let solve the x for the height of 35 degrees elevation and in terms it in d tan35 = x/d x = dtan35

then for the 42 degree and the opp of this situation is the sum of the height of the lighthouse plus x, and we have the value of x so the equation become tan42 = (20 + dtan35) /d solving more by algebra you will get d = 99.9 m far the boat from the cliff
