Three friends, A, B, and C form the vertices (corners) of a triangle on flat ground. Friend “A” is standing directly at the bottom of a sheer cliff. Directly above A, at
the top of the cliff, a fourth friend, “D”, is standing. The distance on the ground
between B and C is 400 m. The angle at “C” between A and B is 35º. The angle
at “B” between A and C is 27º. The angle of elevation from “C” to “D” at the top
of the cliff is 18° Find the angle formed at “D” between “B” and “C”.

Need now max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a) the median of max’s data is 250 b) more than half of the data points max recorded were 177 centimeters. c) a data point chosen at random is as likely to be above the mean as it is to be below the mean. d) every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.
