Mathcad appears to be giving the incorrect answer

Forgive me, I am new to Mathcad. 

 

I have created a simple equation in Matchcad and it appears to be giving me the incorrect answer.

When calculating the same on my calculator or in a relation in Creo I get the answer: 32.2275...

 

Does anyone know why this is the case?

Ah, thank you very much!!

Better don't modify the calculation of v and leave it as it is  but rather define theta the correct way:

Unless otherwise stated Prime assumes angles in radiant. So your definition of theta:=20 was interpreted as 20 rad which is about 1145,9 degree, equivalent to 65.9 degree. Hence the different result.
