refer to right triangle ABC with C = 90degrees. Given a= 2 and b=√5 Find the six trigonometric functions of A. and find the angles A and B

  • trig -

    In terms of angle A, the adjacent is √5, the opposite is 2, and the hypotenuse is 3

    so
    sinA = opposite/hypotenuse = 2/3
    etc.
    (you should definitely know the definitions of the trig ratios)

    for angle A
    sin^-1 (2/3) = 41.8°
    B = 90-A = .....
