Respuesta :
There are two angles m∠14 and m∠13 which are supplementary to angle 14.
Angle
Angle is formed by the intersection of two lines. Two angles are said to be supplementary if both of the angles add up to 180 degrees.
From the diagram:
m∠13 + m∠14 = 180° (sum of angles in a straight line )
Also:
m∠15 + m∠14 = 180° (sum of angles in a straight line )
There are two angles m∠14 and m∠13 which are supplementary to angle 14.
