Question: Warning, solution may have been lost

Hi,

I have a problem solving two equations with trigonometric functions. They are as follows:

eq1:= 9180pi - 16295.070arccos(-1.0 + 0.001356852103xu) + 22.1100sin(-1.0pi + 1.0arccos(-1.0 + 0.001356852103xu))(737.0-xu)+7115.0700arccos(-1.513347022 + 0.002053388090xu) - 14.6100sin(-1.0pi + 1.0arccos(-1.513347022 + 0.002053388090xu))(737.0-xu) + (0.1050As(xu-125)/(1349-xu)) - 0.1050As = 1688

eq2:= 9180pi- 16295.070arccos(-1.0 + 0.001356852103xu) + 22.1100sin(-1.0pi + 1.0arccos(-1.0 + 0.001356852103xu))(737.0-xu)+7115.0700arccos(-1.513347022 + 0.002053388090xu) - 14.6100sin(-1.0pi + 1.0arccos(-1.513347022 + 0.002053388090xu))(737.0-xu))(0.7370-0.0005xu) + (0.064260As(xu-125)/(1349-xu)) + 0.064260As= 16014

Sol:=solve({eq1,eq2},{xu,As})

I tried simplifying it to get rid of the pi, but that doesn't change anything. Additionally to solve the equations, the assumptions that xu en As are > 0 can be used. What do I do wrong?

Thanks for advice in advance.
