Basically just find this angle,
I used the sine rule and got something like 50.8...etc, And when I rounded it off I got 51.
But I dont think its right, Anyone help, I think the red 29 that I've indicated is right because its a parallelogram but if its not then I know I went wrong, Any help on how to solve this.
Thanks
edit: calculated again, I think the right answer was 50*51
Hello, ZettaDigit!
The problem is the dreaded "ambiguous case".
There are two solutions.
Find angle
Code:C o - - - - - - - - - - - o D \ * \ \ x * \ \ * \ \ 5 * \ \ * \ \ * \ \ 29° * \ A o - - - - - - - - - - - o B 8
Law of Sines: .
Therefore: .
But inverse sine can have more than one value.
Hence: .
And the parallelogram looks like this:
Code:C * - - - - - - - - - - - - - - - - - - - * D / * / / 129.1° * / / * / 5 / * / / * / / * / / 29° * / A * - - - - - - - - - - - - - - - - - - - * B 8
