A tower that is 125 feet tall casts a shadow 173 feet long find the angle of elevation of the sun to the nearest degree
1 answer:
Applying the tangent ratio, the angle of elevation of the sun, to the nearest degree, is: 36°.
<h3>What is the Tangent Ratio?</h3>In a right triangle, tan ∅ = opposite length / adjacent length is the tangent ratio.
Given the following:
- Angle of elevation = ∅
- Opposite length = 125 ft
- Adjacent length = 172 ft
Apply the tangent ratio:
tan ∅ = 125/172
tan ∅ = 125/172
∅ = tan^(-1)(125/172)
∅ ≈ 36°

Answer:
A
Step-by-step explanation:
The explicit formula for a geometric sequence is
f(n) = f(1)
where f(1) is the first term and r the common ratio
Here f(1) = 64 and r = =
=
, then
f(n) = 64 → A
