Find y if sin y = cos 48°



Discussion (2)

  • Sin Y = cos 48
    Sin Y = cos 90° - Y
    Cos 90° -Y = cos 48
    Divide by cos
    90°-Y = 48
    -Y = 48 -90
    - Y = -42
    Y = 42

    Cos Y = sin (90 - Y)(complementary angles)
    Y= 48
    Cos 48= Sin (90 - 48)
    Cos 48 = Sin (42)
    Ans = 42 degree (C)
