Explanation / Answer

Ans: Using sine rule: (a/sin a) = ( b/sin b) = ( c/sin c) here we have

(12/sin b) = (15/sin 49) sin b = (12*sin 49)/15 = 0.60376.

So b = arcsin (0.60376) = 37.139 degrees. (arcsin = inverse sin).

Now sum of all angles of triangle = 180 degrees. Angle x = 180-(49+37.139) = 93.861 degrees.

So by sine rule: (x/ sin 93.861) = (15/sin 49) x = (15/sin 49)*sin 93.861 = 19.83
