Math Problem Statement
A rocket fired straight up is tracked by an observer on the ground 1 mi away.
(a) Show that when the angle of elevation is 𝜃, the height of the rocket (in ft) is h = 5280 tan(𝜃).
From the figure, we see that
tan(𝜃) =
h
1
mi
,
so
h
=
(tan(𝜃))
1
mi
=
(tan(𝜃))
1
mi
5280
ft
1 mi
=
ft. (b) Complete the table to find the height of the rocket at the given angles of elevation. (Round your answers to the nearest foot.)
