The answer is c, the average systolic blood pressure of all USA men aged 40-59
A(n)=a(1)+(n-1)d=
a(n)=2+(n-1)2=2+2n-2=2n
Step-by-step explanation:
tan = perpendicular / base
acc. to diagram ,
angle C = 90°
such that
AB is hypotenuse
acc to theta ,
AC is perpendicular and BC is base
therefore
tan theta = AC / BC
tan theta = 8/15
