Step-by-step explanation: 2/-2 is -1
If you do not believe me you can multiple -1 by -2 and you should get positive 2 inside the quotient. :)
Answer:
A
Step-by-step 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
