**Steve**, Wednesday, September 28, 2011 at 11:48pmWell, draw a triangle! I mean, they only gave you two pieces of information. Can't see any way to use it?

At the top of the cliff is point A. At the bottom of the cliff is point B. AB = 45m. Somewhere out along the ground is point C.

Now, angle BAC is 68deg.

BC/45 = tan(68)

BC = 45 tan(68) = 45 * 2.475 = 111.38m
