Actually Welcome to the Concept of the Symmetry,
Option A.) is correct,
=> N has only the Rotational Symmetry.
Use the compound amount formula: A = P(1+r)^t
Here, A = $2700(1+0.07)^3 = $3307.62
Luis will have accumulated $3307.62 to spend on his trib to Belize.
Neagtive means go backwards or oposite
it takes away that many units
Since you have an angle and at least one side you can use either sine, cosine or tan. For this question, you would use sine like above. Hope this helps!
