A) drivers of semi-trucks and other large vehicles pay close attention to signs similar to the one below. these signs indicate a change in the grade or slope of the road. look at the black scalene triangle in the sign. how can the third-angle theorem be applied to find all three angle measurements in the black triangle? b) are the black triangles above congruent or similar? explain.

Suppose that an airline uses a seat width of 16.516.5 in. assume men have hip breadths that are normally distributed with a mean of 14.414.4 in. and a standard deviation of 0.90.9 in. complete parts (a) through (c) below. (a) find the probability that if an individual man is randomly selected, his hip breadth will be greater than 16.516.5 in. the probability is nothing. (round to four decimal places as needed.)
