Discrete fourier transform (DFT) Question

I have already get the waveform of the equation given. But I don't have any idea on how to calculate the magnitude and phase of the spectrum above.

Is that anyone can share the coding in MATLAB to get the magnitude and phase of this spectrum?

Thank you all so much!!!

Check out this example from the angle documentation: https://www.mathworks.com/help/matlab/ref/angle.html#mw_9b727746-7db3-4b26-92f8-cacbefc24cd6. It is practically identical to your problem
