Answer 2

Let the angle be x. According to question,

x + 1/3 (180° - x) = 90°

       x + 60° - x/3 = 90°

                 x - x/3 = 90° - 60°
        
                   2 x/3 = 30°

                      2 x = 90°

                         x = 45°

Hence the angle is 45° and option (d) 45° is correct.
