    Sin 26/79 = Sinx/135 .. cross multiply we get 0.74911 etc, Sin inverse this, we get 48.51 .. its askng the obtuse value, so 48.51 - 360 = 131.5 ... there u go ;) hope i helped then in part c, 131.5+26-180 = 22.5 .. so , Sin90/79 = Sin22.5/x .. cross multiply u get 30.23 .. there u go again :)...
