At this point, the plane started descending. As the plane turned, it’s altitude dropped from 3060 feet to 1650 feet above ground level. Calculate the angle of descent if the plane traveled 0.5 miles (c).

A33 gram sample of a substance that's used to detect explosives has a k-value of 0.1473. n = noekt no = initial mass (at time t = 0) n = mass at time t k = a positive constant that depends on the substance itself and on the units used to measure time t = time, in days
