you can check the example in the picture below, why the cosine of the complementary angle is equals to the sine of its sibling.
The way you asked the question, none of those are the answer. 2.55*10-4 is 21.5, which is not one of the options you provided.
However, you may have meant 2.55*10^-4, in which case it's 0.00025
Well the equation is 6x + x + 19 = 180 or 7x + 19 = 180. You subtract 19 from 180 to get 161. Then you divide 161 by 7 to get x = 23. Finally, you plug x in to get 6(23) + 19 or 157°
