The extensions of the legs ab and cd of a trapezoid abcd intersect at point e. find the lengths of the altitude of △aed drawn to the base ad, if bc=7cm, ad=21cm, and the length of an altitude of a trapezoid is 3cm.

Marcus built a model car that is 4 inches wide. what scale was used to build the car if the actual width of the car is 6 feet? a. 1 in. = 2 ftb. 1 in. = 2.5 ftc. 1 in. = 1.5 ftd. 1 ft = 1.5 in.

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.)

He that is measured at 220° is a reflex angle. the opposite angle is obtuse. find the measure of obtuse .
