i got 53.1 as an answer but on my answer sheet is also has 126.9

How do i get that 126.9?

**drwls**, Thursday, April 15, 2010 at 4:56amBoth answers are correct. sine is positive in the first and second quadrant, and the sine of an angle equals the sine of its supplementary angle.

180.00 - 53.13 = 126.87
