I'm using MathCAD 9.0.0.0. Attached is my program. I need to find theta. Theta should equal 32.6 degrees. How can I get MathCAD to solve for theta?

Thanks,
Brent
As you probably know that the inverse of tan is arctan (in Prime atan) you could use is directly

If you insist that Prime should 'solve' the simple equation, you can use all the methods which I had shown you in the other thread of yours -> Re: Solve variable inside of trig equation?
"root" with interval

"root" with guess value

solve block with "find"

and - again not recommended - the symbolic "solve"

Prime 9 sheet attached
