Trigonometry: The apparent size of a tall building 2 km away is 0.05 radians. What is the building's approximate height?

the answer was 100 m but I was just wondering how they got 100

What are correct trigonometric ratios that could be used to determine the length of ln

Find the greatest common factor of the polynomial: 10x^5+15x^4-25x^3 10x^5 x^3 5x^3 5

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.
