    \[\large y=sin^{-1}(2 sin(x))\] So, what is x? And what do you mean by "construct?"

    Let x to be a given angle I don't know what they mean by construct This is what is given in question (SL Loney)

    If by construct, you mean draw, then it would look like this: |dw:1350575550616:dw|

    Ok @hartnn and @CliffSedge but what about value of y ?

    u directly get the measure of angle y from construction, using protractor(ofcourse knowing angle x), analytically it will be sin^-1(2sin x)

    But it is the question of trigo. equation of SL Loney @hartnn and no answer is given at the end............... And uptill that question there is nothing about constructing angle using protactor and inverse trigonometric functions

    You need more information about x and y to say anything else about it. The diagrams and equations hartnn and I gave are all you can do in this situation given that information.

    I am looking at S.L. Loney. Plane Trigonometry now ( http://books.google.com/books?id=grQUWYejIq4C ), can you let me know what page number you saw this on?

    See proposition 77 on page 76. It seems to be the identical method hartnn and I used.

    from page 77, u just extend the side c 3 times, |dw:1350577118123:dw| then AOB will be required angle
