Answer:
The targeted population is USA residents who died of heart disease.
Step-by-step explanation:
According to this case, "the death rates due to heart disease among the smokers and nonsmokers are compared to see if smoking causes heart disease." This implies that the study targets those USA residents who died of heart disease to find out if the cause of death can be traced to heart disease caused by smoking or not. The main concentration for the study defines the targeted population. It is this group of residents who died of heart disease that is the population of interest. This means that the targeted population is a certain group of the population that share similar characteristics, especially death resulting from heart disease caused by smoking.
angle at a straight line is =180
4+5+x=180
let x be angle at the tower
9+x=180
x=180-9
x=171°
and x is divide in to two then is 2x
there for
2x=171°
x=171/2
x=85.5°
then sin85.5°= 90/y
let y be the unknown feet
0.9969=90/y
y0.9969=90
y=90/0.9969
y=90.3ft.
