You can generate the sine wave using sin() function: https://www.mathworks.com/help/matlab/ref/sin.html. Note that you can get a particular frequency sine wave by using the formula where f is the frequency you want, and t is the vector of time values. Then use awgn(): https://www.mathworks.com/help/comm/ref/awgn.html to add the required level of noise.
