Question
Find the angle which is equal to its supplement.
✓
Answer
Let the measure of the required angle be $x.$
Since it is its own supplement:
$x + x = 180^\circ $
$2x = 180^\circ $
$x = 90^\circ $
$x + x = 180^\circ $
$2x = 180^\circ $
$x = 90^\circ $
Therefore, the required angle is $90^\circ .$
Since it is its own supplement:
$x + x = 180^\circ $
$2x = 180^\circ $
$x = 90^\circ $
$x + x = 180^\circ $
$2x = 180^\circ $
$x = 90^\circ $
Therefore, the required angle is $90^\circ .$
