------------
Equations are solved.
This is not one, there's no equal sign.

I would use a calculator to find the sine.
Enter 49, divide by 3600. (1 degree = 3600 seconds of arc)
Add 12
Find the sine.

convert to Decimal Degrees
49=49%2F360=0.136111111111111 degrees, add to 12 and you have
12.0136111111111111
now find sin%2812.0136111111111111%29
sin%2812.0136111111111111%29=-0.52503778003932432
