Answer:
B. 43°
Explanation:
The angle that forms a linear pair with 133 degrees inside the triangle is
=180°-133°
Similarly, the angle that forms a linear pair with 90degrees inside the triangle is
=180°-90°
[tex]p+(180\degree-133\degree)+(180\degree-90\degree)=180\degree\text{ (sum of angles in a triangle)}[/tex]
We then go ahead to solve for p.
[tex]\begin{gathered} p+47^0+90^0=180^0 \\ p+137^0=180^0 \\ p=180^0-137^0 \\ p=43^0 \end{gathered}[/tex]
The correct choice is B.
