    IN THE CALCULATOR you need to use the ( sin ^-1 X) key.

    Usually they are underlying beneath the (sin x) key, Just use the (second function key) and then the sin key.

    In my calculator I got tetha = 65.06 degrees.

    This is when you use the arcsin function. Set the equation equal to theta like

    theta = arcsin .90675

    theta = 65.06 degrees

    And don't forget to put your calculator in degrees and not radians.

    Have a good day!

    on you calculator use the sin-1 key.I make it 65.06 degrees.

    that's only one value, though. another is 180 - 65.06 = 114.94 degrees.

    starting from those two values you can then add or subtract any multiple of 360 degrees.
