Question

Use the triangle to evaluate each function.

sin(A) =
tan(A) =
sec(A) =

Answer 1

sin (A) = opposite / hypotenuse = BC / AB = 3/5

tan (A) = opposite / adjacent = BC / AC = 3/4

sec (A) = hypotenuse / adjacent = AB / AC = 5/4

Explanation:

Answer 2

Part I

sin(A)= 3/5

tan(B)= 3/4

sec(A)= 5/4

Part II

B. cot(B)
