If measure the 1st qubit of the Bell state in a certain basis and then measure the 2nd qubit in a basis rotated by a certain angle theta, the probability that you will obtain projection to the corresponding vector is equal to the square of sine of theta?

In the context of quantum information and the properties of Bell states, when the 1st qubit of a Bell state is measured in a certain basis and the 2nd qubit is measured in a basis that is rotated by a specific angle theta, the probability of obtaining projection to the corresponding vector is indeed equal
