Answer:

  • Option A

Explanation:

Find the length of AB:

  • AB =
    √(7^2+4^2) =√(65)

Now as we know:

sine = opposite / hypotenuse

  • sin A = 4/
    √(65) = 4
    √(65)/65

cosine = adjacent / hypotenuse

  • cos A = 7/
    √(65) = 7
    √(65)/65

tangent = opposite / adjacent

  • tan A = 4 / 7

Correct choice is A
