I am not sure that I understood your question correctly, so I will make some assumptions. Hopefully, even if they are incorrect, I hope that I will give you enough information to still solve the problem.
Anyhow, here are the assumptions that I made.
1angle40deg means 1 degree 40 minutes, or as expressed as a number 1+40/60
j is the typical electrical engineering way to "name" imaginary number sqrt(-1) usually named "i" by mathematicians.
j2 means (in mathematicians terms) i*2
With these assumtions, here is what I entered to solve the problem:
in CAS mode (press the CAS key): use the csolve function:
