    Do you have any questions about what I wrote below?

    Flip the triangle around its base (within the circle) and look at the resulting figure....

    Hmmmm....you know the central angle is 120 degrees;
    and you know the radius: have you tried calculating
    the segment instead? Here's the formula:

    Got it!

    Hello:

    Thank you!

    Finally, I had the "Aah-Ha" moment.

    For beginners... I think math authors think we know what certain angles are going to be of shapes (like the triangle) when they give us dimensions of objects "not to scale".

    In all, I'm very appreciated of your help.

    How easy was this!!!

    Bye,


    Brett
