Invalid arguments error message in the program below. Advice please on why this is not working.

>	restart: h:=12:base:=7.8:A:=1.12:w:=1.5: lY:=w/sin(A): depth:=(base/2-lY)tan(A): #Set notation brackets - ignores this #solve({tan(x)=2(h-depth-y)/w, z=wcos(A)+wsin(A)/tan(A+x), uY+z+depth=h},{x, y,z}); solve(tan(x)=2(h-depth-y)/w, z=wcos(A)+w*sin(A)/tan(A+x), uY+z+depth=h,{x, y,z});
