Of course not. If the angle is 50 degrees, you must write the angle symbol when using the angle system (that is, write ∠ ABC = 50). If you don't write the symbol of "degree" and write the numerical value directly, then the numerical value is incorrect, because if you only write the numerical value without indicating the unit, the angle is directly regarded as radian. 50 radians = 2864.789 degrees. I hope to adopt with pure hands, thank you.
