An airplane flying at an altitude of 6 miles is on a flight path that passes directly over an observer. If thêta is the angle of elevation from the observer to the plane, find the distance from the observer to the plane when (a) thêta = 30°, (b) thêta = 90°, and (c) thêta = 120°. Show work for each step.

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
