I want to calculate the value of x1 from that equation..So this is one equation and one unknown in it..As it contains theeta so therefore it is a non linear equation..So i have used fsolve for that and it has also calculated the result but the thing is result is not correct....the value of x1 should be 0.16 or closer than that..But i have got 0.0315 so i dont know which mistake i am making...Can anyone help please?

Please don't post a picture of code. A picture is useless, because we cannot copy and paste a picture of code into MATLAB. That forces someone who might otherwise be willing and able to help you, to retype your code without error.

function F=myfun(x)
F=[(0.23544*cos(0))+(0.23544*cos(180))+(0.23544*cos(180))+(1.4715*x(1)*cos(0))];
end

Use cosd instead of cos. cosd assumes the argument is in degrees, cos assumes the argument is in radians.
