When viewing Angel Falls (the world's highest waterfall) from Observation Platform A, located on the

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?
