Data

angle = Ф = 12°

dept = 40 m

distance from the ship to the treasure = ?

Process

To solve this problem use trigonometric functions. The trigonometric function that relates the Opposite side and the adjacent side is tangent.

                      tan Ф = Opposite side / Adjacent side

-Solve for Opposite side

                      Opposite side = Adjacent side x tanФ

-Substitution

                      Opposite side = 40 x tan 12

-Simplification

                       Opposite side = 8.5 m

What would the one-month interest be for a $5,000 credit card balance with a 12% APR?
Ilia_Sergeevich [38]

Answer:

$50

Step-by-step explanation:

Personally I use a debit and I don't "own" my own card so I'm not good with this stuff quite yet. I looked up a calculator though and $50 seems to be it. (minimum time was 3 months so I divided it by 3 to get $50.)

Hopefully this helps! I kind of just thought of what ran through my head so I would say it's an estimate.
