    To answer this, you have to replace each of the choices to x in the equation. If the answer is between 90° and 180°, then that is an obtuse angle which is the correct answer.

    A. 2 (87.6) + 5 = 180.2°

    B. 2 (42.3) + 5 = 89.6°

    C. 2 (75.4) + 5 = 155.8°

    D. 2 (35.2) + 5 = 75.4°

    Therefore, the answer is letter C.
