Answer
$\angle a+\angle b= 47^{\circ}+133^{\circ}=180^{\circ}$
$\angle a+\angle d= 47^{\circ}+133^{\circ}=180^{\circ}$
$\angle c+\angle b= 47^{\circ}+133^{\circ}=180^{\circ}$
$\angle c+\angle d= 47^{\circ}+133^{\circ}=180^{\circ}$
Work Step by Step
Two angles are supplementary if they add up to $180^{\circ}$, which is a straight angle.
In the picture, there are 4 different straight angles, therefore there will be 4 different pairs of supplementary angles.
$\angle a+\angle b= 47^{\circ}+133^{\circ}=180^{\circ}$
$\angle a+\angle d= 47^{\circ}+133^{\circ}=180^{\circ}$
$\angle c+\angle b= 47^{\circ}+133^{\circ}=180^{\circ}$
$\angle c+\angle d= 47^{\circ}+133^{\circ}=180^{\circ}$
