Question

The angle of depression from the top of a flag pole to a point on the ground is 30°. If the point on the ground is 75 feet from the base of the flag pole, how tall is the pole to the nearest foot?

Answer 1

just check work,

Answer 2

\[\tan 30 = \frac{ x }{ 75 }\]
\[(75)(\tan 30) = x\]
\[(75)(.577350269) = x\]
\[43.30 = x\]

Answer 3

\(\tan(30º) = \dfrac{1}{\sqrt{3}}\)

Sometimes, you need the exact value.

Good work.

Answer 4

it wants the exact alue in feet

Answer 5

Value rounded to feet. In this case, you don;'t need the exact value. I's good to know it, though.
