Answer:
The answer to your question is 8.5 m
Step-by-step explanation:
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
106.09x^2 I think this is the answer but just in case do 106.09x106.09 then add the x
If the angles are vertical, they must be equal.
If the angles are supplementary, then they add up to 180 degrees.
If each angles is x (since they are equal)
then
2x=180, or
x=90 °
The angles are each 90 °
