Answer:
for all n>0,
Step-by-step explanation:
Let be the sequence described.
A geometric sequence has the following property: there exists some r (the ratio of the sequence) such that forr all n>0.
To find r, note that
Similarly
Thus for all n>0, and
We know that
tan ∅=opposite side angle ∅/adjacent side angle ∅
adjacent side angle ∅=opposite side angle/tan ∅
in this problem
see the attached figure to better understand the problem
angle ∅=80°
opposite side angle ∅=12 ft (AB)
adjacent side angle ∅=? (AC)
adjacent side angle ∅=12/tan 80°------> 2.12 ft
the answer is
2.12 ft
tan ∅=opposite side angle ∅/adjacent side angle ∅
adjacent side angle ∅=opposite side angle/tan ∅
in this problem
