same level as the bottom of the waterfall, we calculate the angle of elevation to the top of the waterfall to

be 69.30°. From Observation Platform B, which is located on the same level exactly 1000 feet from the

first observation point, we calculate the angle of elevation to the top of the waterfall to be 52.90°. How

high is the waterfall?

**Reiny**, Saturday, June 16, 2012 at 11:27pmYou are obviously looking at or have made a diagram.

let the top of the falls be point C

In triangle ABC

B = 52.9°

A = 110.7° , the supplement of 69.3

then angle C = 16.4°

by the Sine law

AC/sin52.9 = 1000/sin16.4

AC = 2824.8913...

now in the right-angled triangle

sin69.3 = height/2824.8913..

height = 2642.5 feet
