Answer:

A

Explanation:

The angle adjacent to 133 and 133 form a straight angle and are supplementary, hence

adjacent angle = 180° - 133° = 47°

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles. The angle 90 is an exterior angle, thus

p + 47 = 90 ( subtract 47 from both sides )

p = 43° → A
