    Ф = 0.863 radians or 49.46° (degrees)

    Step-by-step explanation:

    We are given:

    sin Ф = 0.76

    We need to find Ф

    Ф = sin^-1 (0.76)

    Ф = 0.863 radians

    Ф = 49.46°

    So, Ф = 0.863 radians or 49.46° (degrees)

    49.46, 130.54 degrees (0 < theta < 360).

    Step-by-step explanation:

    The angle whose sine is 0.76 = 49.46 degrees.

    This is the angle in the first quadrant. The sine is also positive in the second quadrant so another answer is 180 - 49.46 = 130.54 degrees.
