Plot the spectrum of the sampled signal. See attached file for full problem description.

The signal x(t) = 3 + 4cos(10πt) + 5cos(14πt) + 2cos(20πt) is sampled at a rate of 30 samples per second. Plot the spectrum of the sampled signal showing all components for │f │< 80. Could you please explain how x(t) can be reconstructed from the samples?
