How the heck do I find the height of a waterfall?

Johnny Cheng of World of Waterfalls has provided a great image that depicts how to find the height of a waterfall, using some simple measurements and a calculator. You could do this by hand, but why??
b = c(sinθ)
θ = the angle from a level viewing plain to the crest of the waterfall (Inclinometer/Compass)
c = distance found with a Rangefinder
After finding “b“, add it to “d” to find the overall height; “d” is your height, minus about 6 inches for the top of your head to your eyes.
I usually will:
Enter in the angle and hit the “sin” button on the calculator, and then multiply by “c“.
