Triangles A and B are right angled.

a) show that the two shorter sides in triangle A have the same length as the two shorter sides in triangle B.

b) explain why the two triangles are congruent.

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.)

Evaluate the discriminant of each equation. tell how many solutions each equation has and whether the solutions are real or imaginary. x^2 - 4x - 5 = 0

Two years ago a man was six times as old as his daughter. in 18 years he will be twice as old as his daughter. determine their present ages.
