Sin(A) = Opposite/Hypotenuse or Sin(A) = o/h

(1) opposite lenght = 3m and hypotenuse lenght = 5m. Find Angle A

(2) opposite lenght = 2m and hypotenuse lenght = 3m. Find Angle A

(3) opposite lenght = 1m and hypotenuse lenght = 2m. Find Angle A

Cos(A) = Adjacent/Hypotenuse or Cos(A) = a/h

(1) adjacent lenght = 3m and hypotenuse lenght = 5m. Find Angle A

(2) adjacent lenght = 5m and hypotenuse lenght = 7m. Find Angle A

(3) adjacent lenght = 6m and hypotenuse lenght = 15m. Find Angle A

Tan(A) = Opposite/Adjacent or Tan(A) = o/a

(1) Opposite lenght = 1m and adjacent lenght = 2m. Find Angle A

(2) Opposite lenght = 2m and adjacent lenght = 5m. Find Angle A

(3) Opposite lenght = 1m and adjacent lenght = 2m. Find Angle A
