Answer:
1. sin(A) =

2. cos(A) =

3. tan(A) =

4. sin(B) =

5. cos(B) =

6. tan(B) =

Explanation:
Use SOHCAHTOA:
Sine = Opposite/Hypotenuse, Cosine = Adjacent/Hypotenuse, Tangent = Opposite/Adjacent.
1. sin(A) = opposite of A / hypotenuse of A =

2. cos(A) = adjacent of A / hypotenuse of A =

3. tan(A) = opposite of A / adjacent of A =

4. sin(B) = opposite of B / hypotenuse of B =

5. cos(B) = adjacent of B / hypotenuse of B =

6. tan(B) = opposite of B / adjacent of B =
