in radian please

You can put this solution on YOUR website!
sin%28x%29=+-0.8
x=-53.1 degrees
and by identity, 180-x, also solves,
180-x=180-%28-53.1%29=233.1 degrees.
We'll make both values positive.
x=-53.1%2B360=306.9 and x=233.1
To change from degrees to radians use the conversion factor
%282%2Api%29%2F360 radians/degree
x=306.9%2A%282%2Api%29%2F360 radians
x=5.36 radians
x=233.1%2A%282%2Api%29%2F360 radians
x=4.07 radians
