Question

1. identify the angles as complementary or supplementary. then find the missing angle.

Explanation:

Step1: Define supplementary angles

Supplementary angles add up to 180°.

Step2: Set up the equation

Let the missing angle be $x$. We have $x + 127^{\circ}=180^{\circ}$.

Step3: Solve for the missing angle

$x=180^{\circ}- 127^{\circ}$.
$x = 53^{\circ}$.

Answer:

The angles are supplementary and the missing angle is $53^{\circ}$.
